e. Are the resulting statistics representative of the population of all TVs that are 60 inches and​ larger? Choose the best answer below.
 
 
A.
Since the sample is random and the sample size is greater than​ 10, the sample can be considered to be representative of the population.
 
B.
Since the sample is random and the sample size is greater than​ 10, the sample should not be considered to be representative of the population.
 
C.
