A sample of size n= 96 is drawn from a normal population whose standard deviation is o = 7.8. The sample mean is x = 49.32. Part 1 of 2 (a) Construct a 99% confidence interval for u. Round the answer to at least two decimal places. A 99% confidence interval for the mean is LE Part 2 of 2 (b) If the population were not approximately normal, would the confidence interval constructed in part (a) be valid? Explain.
