A sample of n =39 observations has a sample mean of x
Chapter 8, Problem 8.2.2(choose chapter or problem)
A sample of n =39 observations has a sample mean of x =5532 and a sample standard deviation of s =287.8. Consider the hypothesis testing problems: (a) H0 : =5680 versus HA : =5680 (b) H0 : 5450 versus HA : >5450 In each case, write down an expression for the p-value. What do the critical points in Table III tell you about the p-values? Use a computer package to evaluate the p-values exactly.
