Suppose that the weekly amount of down time in hours, Y, for an industrial machine follows a Gamma distribution with mean lb = aß = 2ß, where B is an unknown parameter. The weekly loss in dollars, X, to the industrial operation as a result of this down time is given by X = 3Y + 30. Based on a sample of n observations, find an unbiased estimator for of as a function of the statistic y.

A soda bottling plant fills cans labeled to contain 12 ounces of soda. The filling machine varies and does not fill each can with exactly 12 ounces. To determine if the filling machine needs adjustment, each day the quality control manager measures the amount of soda per can for a random sample of 50 cans. Experience shows that its filling machines have a known population standard deviation of 0.35 ounces. In today's sample of 50 cans of soda, the sample...
