16. For her final project, Stacy plans on surveying a random sample of 50 students on whether they plan to leave town for Spring Break. Based on past years, she guesses that about
85% of the students will go somewhere. Can she use a Normal model for the sampling model?
a) Yes, because np = 42.5, which is greater than 10.
b) Yes, because a Normal model always applies to sample proportions.
c) No, because a Normal model is not appropriate for a binomial situation.
d) No, because ng = 7.5, which is less than 10.
