Applying the Central Limit Theorem, suppose that personal computers (PC) have a mean of weight of 7.5 pounds with a standard deviation of 1.1 pounds. If you take a sample of the weight of 50 different brands of PC, the sample standard deviation is: Select one: a. 7.5 1.1 7.51.1 b. 1.1 50 √ 1.150 c. 7.5+1.1 7.5+1.1
