Question 869861: In a recent survey, 90 percent of the community favored building a police substation in the neighborhood. You randomly select 16 citizens and ask each if he or she thinks the community needs a police substation. Decide whether you can use the normal distribution to approximate the binomial distribution. If so, find the mean and the standard deviation. If not, explain why.
Hi
Note: We can use the normal distribution as a close approximation to the
binomial distribution whenever np ≥ 5 and nq ≥ 5.
nq = 16(.10) = 1.60
No, we cannot use the normal distribution to approximate this binomial distribution
