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 2 of μ? 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.)
