A manufacturer of band saws wants to estimate the average repair cost per month for the saws he has sold to certain industries. He cannot obtain a repair cost for each saw, but he can obtain the total amount spent for saw repairs and the number of saws owned by each industry. Thus, he decides to use cluster sampling, with each industry as a cluster. The manufacturer selects a simple random sample of n 5 from the N = 96 industries he services. The data on total cost of repairs per industry and number of saws per industry are as given in the following table. Industry Number of saws(m) Total repair cost (y) 1 12 280 14 240 3 3 45 4 15 60 230 month and place a hound on the error O
