Consider the situation in Review Exercise 8.74. Suppose a considerable quality effort is conducted to "tighten'' the variability in the system. Following the effort, a random sample of size 40 is taken from the new assembly line and the sample variance s* = 0.188 ounces2. Do we have strong numerical evidence that a2 has been reduced below 1.0? Consider the probability P(S2 < 0.188 | a2 = 1.0) and give conclusion.
