2. 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) 5 (D) The mean is 27.5, and the standard deviation is √5(27.5)(72.5). (E) The mean is 27.5, and the standard deviation is 27.5(72.5) 5
