8-94. Consider the bottle-wall thickness measurements described in Exercise 8-42. (a) Compute a 90% tolerance interval on bottle-wall thickness that has confidence level 90%. (b) Compute a 90% lower tolerance bound on bottle-wall thickness that has confidence level 90%. Why would a lower tolerance bound likely be of interest here?
