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, 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 90% confident that your estimate is within 4 of u? Use the value 23 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.) 2 Check ace Oll ^ 6 tab esc ! 1 9 a @ 2 W S S # 3 e C d $ 4 r % 5 f t g y & 7 h
