instead of testing a hypothesis, you might

prefer to construct a confidence interval for the mean weight of all 2-pound boxes of

candy during a recent production shift.

(a) Given a population standard deviation of .30 ounce and a sample mean weight of

33.09 ounces for a random sample of 36 candy boxes, construct a 95 percent confidence

interval.

(b) Interpret this interval, given the manufacturer's desire to produce boxes of candy

that, on the average, exceed 32 ounces.
