A random sample of 20 ages of world leaders yielded the following data: 54 66 53 49 50 65 82 62 65 63 47 76 68 71 72 78 77 88 72 59 a) Determine a 95% confidence interval for all the mean ages,u, for all world leaders. Assume the population standard deviation is 11.2 years. (Note: the sum of the data is 1317.) b) Interpret your answer to part (a).
