A bag contains chips of which 27.5 percent are blue. A random sample of 5 chips will be selected one at a time and with replacement. What are the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5?

A bag contains chips of which 27.5 percent are blue. A random sample of 5 chips will be selected one at a time and
with replacement. What are the mean and standard deviation of the sampling distribution of the sample proportion
of blue chips for samples of size 5 ?
(A) The mean is 5(0.275), and the standard deviation is √5(0.275) (0.725).
27.5
(B) The mean is 0.275, and the standard deviation is √5(0.275) (0.725).
((c)) The mean is 0.275, and the standard deviation is
0.275(0.725)
