a. Under the same conditions as those leading to the interval

(7.5), . Use this to derive a one-sided interval for m that has infinite width and provides a lower confidence bound on m. What is this interval for the data in Exercise 5(a)?

b. Generalize the result of part

(a) to obtain a lower bound with confidence level .

c. What is an analogous interval to that of part

(b) that provides an upper bound on m? Compute this 99% interval for the data of Exercise 4(a).
