Suppose that you are testing the hypotheses H0?: mu =14 vs. HA?: mu >14. A sample of size 16 results in a sample mean of 14.5 and a sample standard deviation of 1.7
?a) What is the standard error of the? mean?
?b) What is the critical value of? t* for a 90?% confidence? interval?
?c) Construct a 90?% confidence interval for mu μ
