Question: What is the probability that an X from a random sample of 4 observations (n = 4) will fall within these limits if the mean

What is the probability that an X from a random sample of 4 observations (n = 4)

will fall within these limits if the mean of the population actually is at 31,000 pounds? That is, what is B (that is, the probability of a type II error) if w = 31,000?

What is B if wp = 30,000?
