I test to determine if the average size of

all Hillsborough County apartments

exceeds 1025 square feet. The following

printout is obtained:

distribution with 24 degrees of freedom.

None. The Central Limit Theorem applies

and no other assumptions are needed.

apartments needs to be approximately
