We can conclude that we are 95% confident that the true proportion of American adults who believe in aliens lies between 0.63 and 0.81 is the answer.

In a survey conducted on an SRS of 200 American adults, 72% of them said they believed in aliens. We have to provide a 95% confidence interval for the percent of American adults who believe in aliens. A confidence interval is a range of values that estimates a population parameter with a specific level of confidence.

The formula for a confidence interval for a population proportion is: p ± zα/2  ×  √((p(1-p))/n) where, p is the sample proportion, zα/2 is the z-value for the level of confidence, and n is the sample size.

Here, p = 0.72, n = 200, α = 1 - 0.95 = 0.05/2 = 0.025 (for a 95% confidence interval), and zα/2 = 1.96 (from the z-table).

Now, let's plug in the values: p ± zα/2  ×  √((p(1-p))/n) = 0.72 ± 1.96 × √((0.72(1 - 0.72))/200)= 0.72 ± 0.0894

Thus, the 95% confidence interval for the percent of American adults who believe in aliens is (0.63, 0.81).

Therefore, we can conclude that we are 95% confident that the true proportion of American adults who believe in aliens lies between 0.63 and 0.81.

Step-by-step explanation:

In the proportional relationship, the value of y when x = 7 is 28.

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value.

Therefore, the value of y is directly proportional to the value of x. When x = 3.5, the value of y is 14.

Hence,

y ∝ x

y = kx

where

when y = 14 , x = 3.5

14 = 3.5k

k = 14 / 3.5

k = 4

Therefore,  let's find the value of y when x = 7.

y = 4 × 7

y = 28

Answer:

- \(\frac{1}{2}\)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x - y = 5 ( subtract 2x from both sides )

- y = - 2x + 5 ( multiply through by - 1 )

y = 2x - 5 ← in slope- intercept form

with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{2}\)

According to the table the independent variable remains constant for change in the dependent variable.

There are dependent and independent variables in statistical modelling, experimental sciences, and mathematical modelling.

Dependent variables get their name from the fact that during an experiment, their values are assessed under the assumption or obligation that they rely on the dependent variable as a result of a rule or law. Independent variables are ones that are not seen as being reliant on any other factors in the context of the experiment in question.

In this respect, frequent independent variables include things like space, density, mass, rate of fluid flow, and a particular value among some observed phenomena of interest.

we can calculate the test statistic as follows:

t = (mean A - mean B) / √((sA² / nA) + (sB² / nB))

What is probability?

Probability is a measure or quantification of the likelihood of an event occurring. It is a numerical value assigned to an event, indicating the degree of uncertainty or chance associated with that event. Probability is commonly expressed as a number between 0 and 1, where 0 represents an impossible event, 1 represents a certain event, and values in between indicate varying degrees of likelihood.

To determine if the data suggests that the two methods provide the same mean value for natural vibration frequency, we can perform a hypothesis test.

Let's define the hypotheses:

H0: The mean value for natural vibration frequency using Method A is equal to the mean value using Method B.

H1: The mean value for natural vibration frequency using Method A is not equal to the mean value using Method B.

We can use a two-sample t-test to compare the means. We calculate the test statistic and the p-value to make our decision.

If we have the sample means, standard deviations, and sample sizes for both methods, we can calculate the test statistic as follows:

t = (mean A - mean B) / √((sA² / nA) + (sB² / nB))

Here, mean A and mean B are the sample means, sA and sB are the sample standard deviations, and nA and nB are the sample sizes for Methods A and B, respectively.

The p-value corresponds to the probability of observing a test statistic as extreme as the one calculated, assuming the null hypothesis is true.

To find the interval for the p-value, we need more information such as the sample means, standard deviations, and sample sizes for both methods. With that information, we can perform the calculations and determine the p-value interval.

Hence, we can calculate the test statistic as follows:

t = (mean A - mean B) / √((sA² / nA) + (sB² / nB))

(a) The sequence (aₙ)ₙ₌₁ is decreasing.

(b) Yes, (aₙ)ₙ₌₁ is bounded, with upper bound M and lower bound 0, since limₙ→∞ aₙ = 0.

(a) The sequence (aₙ)ₙ₌₁ is decreasing. To prove this, we can calculate the ratio of consecutive terms:

aₙ₊₁/aₙ = (n+1)e^-(n+1)/(ne^-n) = (n+1)e^-(n+1)e^n = (n+1)/ne = 1 + 1/n
Since (n+1)/n is always greater than 1 for n ≥ 1, the ratio is greater than 1. Therefore, aₙ₊₁ > aₙ, showing that the sequence is decreasing.

(b) The sequence (aₙ)ₙ₌₁ is bounded. To find its bounds, let's consider the limit of the sequence as n approaches infinity:
limₙ→∞ aₙ = limₙ→∞ ne^(-n) = 0

Since the limit of the sequence is zero, the sequence is bounded above by any positive number, and bounded below by zero. In other words, the upper bound is any positive number M, and the lower bound is zero.

Answer:

Step-by-step explanation:

You want to know how far Dylan travelled if he drove 50 mph for 3.5 hours and 65 mph for 2 hours.

Distance is the product of speed and time. The total distance Dylan travelled will be the sum of lengths of the legs of his trip.

  distance = speed · time

  total distance = speed1 · time1 + speed2 · time2

  = (50 mi/h)(3.5 h) +(65 mi/h)(2 h) = 305 mi

Dylan travelled a total of 305 miles.

The value of P(0) and P(6) of The Polynomial Function above are 2 and 253/2 respectively.

Polynomial function refers to the algebraic expression that consists of several terms.

Polynomial function can be of different degrees, like linear polynomial (degree 1), quadratic polynomial (degree 2), cubic polynomial (degree 3), and so on.

The given polynomial function is P(w) = 6w² - 20w + 2.

To find P(6), substitute w = 6 in P(w).

Therefore,P(6) = 6(6)² - 20(6) + 2P(6) = 6(36) - 120 + 2P(6) = 216 - 120 + 2P(6) = 96

Adding P(6) = 349 to this equation, we get:2P(6) = 349 - 96 = 253

Therefore, P(6) = 253/2

Now, to find P(0), substitute w = 0 in P(w).

Therefore, P(0) = 6(0)² - 20(0) + 2 = 2

Therefore, P(0) = 2
