Describe the sampling distribution of p Assume the size of t

Describe the sampling distribution of p. Assume the size of the population is 15,000. n=600,p=0.4 Choose the phrase that best describes the shape of the sampling distribution of p below. A. Not normal because n

Solution

Answer : D.

n=600

p=0.4

0.05N = 0.05 * 15000 = 750

600<750 => n<=0.05N True

np(1-p) = 600 * 0.4 * 0.6 = 144

144>10 => np(1-p) >= 10 True

Option D Answer
