A personality test has a subsection designed to assess the "honesty" of the test-taker. Suppose that you're interested in the mean score, m, 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 m. What is the minimum sample size needed in order for you to be 90% confident that your estimate is within 3ofm? Use the value 23 for the population standard deviation of scores on this subsection.
