It is known that 20% of televisions produced by a given manufacturer have a minor defect. A retailer buys 100 (randomly chosen) televisions from the manufacturer. Using the normal approximation to the distribution of the sample proportion, and ignoring continuity correction, the probability that 15% or more of these 100 televisions have minor defects is approximately (Hint: In this case the variance of the sample proportion is 0.0016; i.s. the standard deviation of the sample proportion is 0.04)

a)0.1587

b)0.8944

c)0.1056

d)0.3944
