Question

A simple random sample of 800 elements generates a sample proportion p = 0.64. (round your answers to four decimal places.)

Answer 1

We can use the formula p' ± z * sqrt((p' * q') / n) to find the confidence interval for the population proportion.

Step-by-step explanation:

In this problem, we are given a simple random sample with 800 elements and a sample proportion of 0.64. The sample proportion, denoted by p', is the point estimate for the true population proportion. To find the confidence interval for the population proportion, we can use the formula:

p' ± z * sqrt((p' * q') / n)

In this formula, p' is the sample proportion, q' is the complement of the sample proportion (1 - p'), n is the sample size, and z is the z-score corresponding to the desired confidence level.
