The standard deviation of test scores on a certain achievement test is 10.8. A random sample of 70 scores on this test had a mean of 76.4. Based on this sample, find a 95% confidence interval for the true mean of all scores. Then give its lower limit and upper limit. 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: I Upper limit: I
