The critical t-value corresponding to a 90% confidence level and a sample size of n = 15 is: D. 1.761.

To find the critical t-value corresponding to a 90% confidence level and a sample size of n = 15, we'll follow these steps:

1. Determine the degrees of freedom (df): Since the sample size is n = 15, the degrees of freedom will be df = n - 1 = 15 - 1 = 14.

2. Determine the confidence level: The question asks for a 90% confidence level, which means that there is 10% of uncertainty. We need to divide this remaining 10% by 2 because it's a two-tailed test (5% on each side of the distribution). Therefore, we're looking for the t-value that corresponds to 95% of the area under the t-distribution curve.

3. Use a t-table or calculator: You can either use a t-table or an online calculator to find the critical t-value associated with the 95% confidence level and 14 degrees of freedom. The closest value that you will find in the t-table or calculator is 1.761.

So, the correct answer is: D. 1.761.

Answer:

D. subtract 31 from both sides

you cant combine cuz theyre not like terms and you have to undo the constant number before you undo the second term in the equation so you will end up needing to do letter choice D first.

Step-by-step explanation:

hope this helped a little bit :)

======================================================

Explanation:

The expression 31-12t is the same as 31+(-12t). Adding a negative is the same as subtracting a positive.

Then we can flip the two terms getting -12t+31. This is because we can add two numbers in any order.

So we're effectively solving -12t+31 = 211

The first step is to subtract 31 from both sides to undo the +31. We follow PEMDAS in reverse to isolate the variable.

Answer:

\(174 cm^{2}\)

Step-by-step explanation:

There are two triangles and two rectangles in the figure.

To find the area of the triangles:

6 x 9 = \(54cm^{2}\)

To find the area of the rectangles:

9 x 8 = \(72cm^{2}\)

6 x 8 = \(48cm^{2}\)

Add all of this together for your answer:

54 + 72 + 48 = \(174cm^{2}\)

The associated doubling time is also approximately 27.725 (rounded to three significant digits).

To find the associated half-life time or doubling time, we first need to understand what these terms mean.
Half-life time (th) is the amount of time it takes for half of a substance to decay or be eliminated.

In this case, we are dealing with exponential decay, so we can use the formula:
q = q0 * e^(-kt)

where q is the amount of substance remaining at time t, q0 is the initial amount of substance, k is the decay constant, and e is Euler's number (approximately equal to 2.71828).

We are given the equation q = 800e^(-0.025t), which means that the initial amount of substance (q0) is 800 and the decay constant (k) is 0.025.

To find the half-life time, we need to find the value of t when q = q0/2:
q0/2 = 800/2 = 400
400 = 800e^(-0.025t)

Dividing both sides by 800, we get:
0.5 = e^(-0.025t)

Taking the natural logarithm of both sides, we get:
ln(0.5) = -0.025t

Solving for t, we get:
t = ln(0.5)/(-0.025)

Using a calculator to evaluate this expression, we get:
t ≈ 27.725

Therefore, the associated half-life time is approximately 27.725 (rounded to three significant digits).

Doubling time (td) is the amount of time it takes for a substance to double in amount. In this case, we can use the formula:
q = q0 * e^(kt)

where k is the growth constant (since we are looking at the increase in amount rather than the decrease).

To find the doubling time, we need to find the value of t when q = 2q0:
2q0 = 2 * 800 = 1600
1600 = 800e^(0.025t)

Dividing both sides by 800, we get:
2 = e^(0.025t)

Taking the natural logarithm of both sides, we get:
ln(2) = 0.025t

Solving for t, we get:
t = ln(2)/0.025

Using a calculator to evaluate this expression, we get:
t ≈ 27.725

Therefore, the associated doubling time is also approximately 27.725 (rounded to three significant digits).

Step-by-step explanation:

the nine is worth 0.009

Answer:

7.079

Step-by-step explanation:

In the provided numbers, the 9 has the least value in 7.079. In this number, 9 is in the thousandths place, which is a lower place value than in the other numbers. Here's why:

In 0.9, the 9 is in the tenths place, which has a value of 0.9.

In 0.29, the 9 is in the hundredths place, which has a value of 0.09.

In 7.079, the 9 is in the thousandths place, which has a value of 0.009.

In 9.1, the 9 is in the ones place, which has a value of 9.

Therefore, in 7.079, the 9 has the least value.

The largest open interval where the function f(x) = 1/(x^2+1) is increasing is (-∞, 0) ∪ (0, ∞). On this interval, the function is increasing from negative infinity to zero and from zero to positive infinity.

Explanation:

To find where the function is increasing, we need to find where the first derivative of the function is positive. Taking the derivative of f(x), we get:

f'(x) = (-2x) / (x^2 + 1)^2

The denominator of this expression is always positive, so the sign of f'(x) is determined by the numerator. The numerator is negative for x < 0 and positive for x > 0. Therefore, f(x) is decreasing on (-∞, 0) and increasing on (0, ∞).

We also need to check the endpoints of these intervals to make sure that the function is increasing on the entire interval. As x approaches negative infinity, the function approaches 0, and as x approaches positive infinity, the function approaches 0. Therefore, the function is increasing on (-∞, 0) ∪ (0, ∞).

In summary, the largest open interval where the function f(x) = 1/(x^2+1) is increasing is (-∞, 0) ∪ (0, ∞). On this interval, the function is increasing from negative infinity to zero and from zero to positive infinity.

The pattern in y = x² exhibits a nonlinear increase in y as x increases, forming a U-shaped curve, while the pattern in y = 15 + x shows a linear increase in y as x increases at a constant rate.

The patterns in the equations y = x² and y = 15 + x differ in terms of the direction of change. In the equation y = x², the pattern shows an increase in y as x increases.

As x increases from negative to positive values, the corresponding y values also increase, forming a symmetric U-shaped curve. The rate of increase for y becomes steeper as x moves further away from zero.

On the other hand, in the equation y = 15 + x, the pattern shows a linear increase in y as x increases. As x increases, the corresponding y values increase in a straight line.

We can reject the null hypothesis in favor of the alternative hypothesis.

To test the hardware store manager's claim that the new light bulb model has a longer average lifetime, we should set up a hypothesis test.

The null hypothesis (H0) and the alternative hypothesis (H1) should be as follows:

H0: The average lifetime of the new light bulb model is equal to the average lifetime of the certain type of light bulb (μ = 1000 hours).
H1: The average lifetime of the new light bulb model is greater than the average lifetime of the certain type of light bulb (μ > 1000 hours).

We are given the mean (μ = 1000 hours) and standard deviation (σ = 110 hours) of the certain type of light bulb, and a sample of 10 light bulbs from the new model. To perform the hypothesis test, we will calculate the sample mean, compare it to the population mean, and use the standard deviation to determine if the difference is statistically significant.

The given statement is False. A test statistic based on point estimation is not used to construct the decision rule which defines the rejection region.

In hypothesis testing, a test statistic is calculated using sample data and a specific hypothesis to assess the strength of evidence against the null hypothesis. The decision rule, which determines whether to reject or fail to reject the null hypothesis, is based on the test statistic's distribution under the null hypothesis, rather than the point estimate itself.

The construction of the decision rule involves selecting a significance level (alpha), which represents the probability of rejecting the null hypothesis when it is actually true. The rejection region is determined based on the chosen significance level and the distribution of the test statistic. If the calculated test statistic falls within the rejection region, the null hypothesis is rejected; otherwise, it is not rejected.

Point estimation, on the other hand, is used to estimate an unknown parameter of interest, such as the population mean or proportion, based on sample data. It involves calculating a single value (point estimate) that represents the best guess for the parameter value. The point estimate is not directly involved in constructing the decision rule or defining the rejection region in hypothesis testing.

False. A test statistic based on point estimation is not used to construct the decision rule that defines the rejection region.

The process of hypothesis testing involves constructing a decision rule to determine whether to accept or reject a null hypothesis based on sample data. The decision rule is typically defined using a critical region or rejection region, which is a range of values for the test statistic.

Point estimation, on the other hand, is a method used to estimate an unknown population parameter based on sample data. It involves calculating a single value (point estimate) that serves as an estimate of the population parameter.

While point estimation and hypothesis testing are both important concepts in statistics, they serve different purposes. Point estimation is used to estimate population parameters, whereas hypothesis testing involves making decisions based on sample data.

The decision rule for hypothesis testing is typically constructed based on the significance level (alpha) and the distribution of the test statistic, such as the t-distribution or the standard normal distribution. The test statistic is calculated using sample data and compared to critical values or calculated p-values to determine whether to reject the null hypothesis.

Therefore, the statement that a test statistic based on point estimation is used to construct the decision rule defining the rejection region is false.

The correct option is "the standard error is the standard deviation of the sampling distribution." Correct option is A.

The standard error is a measure of the variability of a sampling distribution, which is the distribution of sample statistics (e.g., mean, proportion) that would be obtained from multiple random samples of the same size from the same population.

The standard error represents the standard deviation of the sampling distribution, and it provides a measure of the precision of the sample statistic in estimating the population parameter.

The standard error is not the same as the standard deviation of the sample, which is a measure of the variability of the individual observations in the sample.

The standard deviation of the sample is typically used to estimate the standard deviation of the population, while the standard error is used to estimate the variability of the sample statistic and to construct confidence intervals or perform hypothesis tests.
