Exercise 13 of Chapter 1 presented a sample of n = 153 observations on ultimate tensile strength, and Exercise 17
a. Is any assumption about the tensile-strength distribution required prior to calculating a lower prediction bound for the tensile strength of the next specimen selected using the method described in this section? Explain.
b. Use a statistical software package to investigate the plausibility of a normal population distribution.
c. Calculate a lower prediction bound with a prediction level of 95% for the ultimate tensile strength of the next specimen selected.
