F 1 -4 5 6 7 8 9 10 Suppose that a random sample of 14 adults has a mean score of 76 on a standardized personality test, with a standard deviation of 8. (A higher score indicates a more personable participant. ) If we assume that scores on this test are normally distributed, find a 90% confidence interval for the mean score of all takers of this test. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas,) Lower limit: 1 X ? Upper limit
