A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, μ, on this subsection among the general population. You decide that you'll use the mean of a random sample of scores on this subsection to estimate μ. What is the minimum sample size needed in order for you to be 99% confident that your estimate is within 5 of u? Use the value 22 for the population standard deviation of scores on this subsection. Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements). (If necessary, consult a list of formulas.) 00 X

Question
A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, u, on this subsection
among the general population. You decide that you'll use the mean of a random sample of scores on this subsection to estimate μ. What is the minimum sample
size needed in order for you to be 99% confident that your estimate is within 5 of u? Use the value 22 for the population standard deviation of scores on this
subsection.

Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole
number that satisfies the requirements).
