how do we check for normality of the sampling distribution of for a one sample z confidence interval for proportions? group of answer choices large sample size (n>30) no skewness or outliers in sample data n > 10 and n(1- ) > 10 n > 10 and n(1- ) > 10
To check the normality of the sampling distribution for a one-sample z confidence interval for proportions, the sample size should be large (typically n > 30), and the number of successes and failures in the sample should both be at least 10.
To check for normality of the sampling distribution for a one-sample z confidence interval for proportions, we need to ensure that the following conditions are met:
Large sample size: The sample size should be sufficiently large (typically n > 30). This is because the central limit theorem states that for large enough sample sizes, the sampling distribution of the sample proportion will be approximately normal, regardless of the underlying distribution of the population.
Success-Failure Condition: The number of successes (np) and failures (n(1-p)) in the sample should both be at least 10. This condition ensures that the binomial distribution of the sample proportion is approximately normal.
If these conditions are met, then we can assume that the sampling distribution of the sample proportion is approximately normal, and we can proceed to construct a one-sample z confidence interval for proportions.

Hello There!
We are given that AC and BD are diagonals of a rectangle
If you didn't know diagonals are congruent
So given that BC = 56 and AC = 2x + 10 we can use this equation to solve for x
56 = 2x + 10
now we solve for x
step 1 subtract 10 from each side
56 - 10 = 46
10 - 10 cancels out
now we have 46 = 2x
step 2 divide each side by 2
46/2=23

A car originally costs $20,000. Its price went up by 20% and then by another $8,000. How much did the price go up as a percentage of the original price? O 50%O 55%O 60% O 65%
The percentage by which the price of the car went up from the original price is 60% (third option)
What is the percent increase?The first step is to determine the price of the car after the percentage increase. Percentage is the fraction of a number as a value out of 100. The sign that is used to represent percentage is %.
Price of the car after the percentage increase = (1 + percent increase/100) x original cost of the car
Price of the car after the percentage increase = (1 + 20/100) x 20,000
Price of the car after the percentage increase = (1 + 0.2) x 20,000
Price of the car after the percentage increase = 1.2 x 20,000 = $24,000
Price after the $8,000 increase = $24,000 + 8,000 = $32,000
Percentage of the original price = (32,000 / 20,000) - 1 = 0.60 = 60%

You will be catering a private party for 12 people. You decide to make 11 / 2-ounce cranberry-orange muffins, and you estimate that each person at the party will have three muffins each. Your recipe makes 15 pounds of dough and calls for 4 pounds of cranberries. How many ounces of cranberries will you need for the muffins for this party?
The proportion of cranberries required for the muffins is 4 pounds x 16 ounces/pound = 64 ounces of cranberries. Therefore, to make the muffins for the party, you will need 64 ounces of cranberries.
To calculate the amount of cranberries needed for the muffins at a party of 12 people, making 11/2-ounce muffins and assuming each person will have three muffins, we need to convert the measurements and quantities.
Given that each muffin weighs 11/2 ounces, and each person will have three muffins, we can calculate the total weight of muffins needed. 11/2 ounces is equivalent to 1.5 ounces, so each person will consume 1.5 ounces x 3 muffins = 4.5 ounces of muffins.
For a party of 12 people, the total amount of muffins required is 4.5 ounces/person x 12 people = 54 ounces of muffins.
Now, to determine the amount of cranberries needed for the muffins, we need to consider the recipe's proportion. The recipe makes 15 pounds of dough and calls for 4 pounds of cranberries. To convert pounds to ounces, we know that 1 pound is equal to 16 ounces.

subtract $119 from both sides:
3.75x + $119 - $119 = $400.25 - $119
3.75x = $281.85
divide both sides by 3.75
3.75x/3.75 = $281.85/3.75

true or false let a be a real square matrix. if a is diagonalizable then a is symmetric
False. let a be a real square matrix. if a is diagonalizable then a is symmetric
Explanation: Diagonalizability and symmetry are two different properties of a square matrix. A real square matrix A is diagonalizable if it can be transformed into a diagonal matrix D through a similarity transformation with an invertible matrix P, i.e., A = PDP^(-1). A matrix is symmetric if A = A^T, where A^T is the transpose of A.
While it is true that every symmetric matrix is diagonalizable, the converse is not necessarily true. In other words, not every diagonalizable matrix has to be symmetric.
Conclusion: The statement "if A is diagonalizable then A is symmetric" is false because diagonalizability does not guarantee symmetry.

Suppose that the number P(t) of bacteria in a culture after t days is given by the formula
P(t) = 95 (1.53)^t
How long does it take for the population to triple in size?
The answer indicates that it will take 2.38 yrs to for population to treble in size.
Which demographic do you refer to?A population is any large group that has at least one resource is common. People do not make up all populations. Population numbers can include, but aren't limited to, people, animals, groups, organizations, buildings, houses, trucks, farms, and things.
Let's call the population after it has tripled "P_triple". Then:
P(t) = 3P(0) = 3 * 95
P_triple = 285
We want to find the time t such that P(t) = 285, so we'll set the two expressions equal to each other:
95 (1.53)^t = 285
Dividing both sides by 95:
(1.53)^t = 3
Taking the natural logarithm of both sides:
t = log(3) / log(1.53)
Approximating using a calculator:
t = approximately 2.38 years
So it will take approximately 2.38 years for the population to triple in size.

What is her expected profit? The antique jewelry dealer's expected profit is dollars. (Type an integer or a decimal. Round to the nearest dollar as needed.)
The antique jewelry dealer's expected profit is $88, calculated by multiplying each profit outcome by its probability and summing them up.
To calculate the expected profit, we multiply each profit outcome by its probability and sum them up.
Profit of $250:
0.22 (probability) * $250 (profit) = $55
Profit of $150:
0.30 * $150 = $45
Break-even:
0.40 * $0 = $0
Loss of $150:
0.08 * (-$150) = -$12
