A national caterer determined that 87% of the people who sampled their food said that it was delicious. A random sample of 144 people is obtained from a population of 6000. The 144 people are asked to sample the caterer's food. If p is the sample proportion saying that the food is delicious, what conditions need to be satisfied in order for the sampling distribution of p to be approximately normal? O npqs 10; 20n > N normal probability plot is approx. linear O t-distribution to be normal O npq2 10; n <.05n>
