An existing inventory for a test measuring self-esteem indicates that the scores have a standard deviation of
10
. A psychologist gave the self-esteem test to a random sample of
100
individuals, and their mean score was
65
. Construct a
99%
confidence interval for the true mean of all test scores. Then complete the table below.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)
