example 12.14) Suppose a company manufacturing light bulbs is using two different processes A and B. The life of the light bulbs of process A has a normal distribution with mean µ¡ and standard deviation O1. Similarly, for process B, it is and 02. The data pertaining to the two processes are given below: Sample A Sample B n, = 16 X, = 1200 hr O, = 60 hr N2 = 21 X2 = 1300 hr O2 = 50 hr We have to test the hypothesis that the variability of the two processes is the same.
