Show how a 100( 1 – α )% t CI for can be obtained. Then compute a 95% interval for using the data from Exercise 19. [Hint: With , the result of Exercise 24(a) indicates how to obtain . Then compute and and obtain an estimate of by using to estimate σ (which identifies the appropriate number of df).]
