Data was collected on physical characteristics of Division I starting football players in the 1988 football season. It was reported that the mean weight of all starters on Division I teams in 1988 was 105 kg. A random sample of 33 starting players from Division II teams in 1988 resulted in a sample mean weight of 103.3 kg. Suppose that the standard deviation of weights of all starters on Division II teams in 1988 is known to be 16.3 kg. Is there sufficient evidence to conclude that the mean weight of Division II starters in 1988 is different than 105 kg, the mean weight of Division I starters?

In order to perform this hypothesis test, in addition to having a random sample, what other assumption must be met?

a. n must be 2 >=10
b. n must be 2>= 15
с. n must be >=30
d. n must be =<30
