Choudhury's bowling ball factory in Illinois makes bowling balls of adult size and weight only. The standard deviation in the weight of a bowling ball produced at the factory is known to be 0.39 pounds. Each day for 24 days, the average weight, in pounds, of 9 of the bowling balls produced that day has been assessed as follows: Average (ib.) Day 7 8 9 Average (ib.) Day 1 11.8 2 3 12.1 4 12.0 5 12.1 6 12.1 11.9 12.1 12.0 11.9 11.9 12.1 12.1 Average (lb.) Day 13 12.0 14 11.9 15 12.0 16 12.0 17 12.0 18 12.0 Average (Ib.)
