Question

describe the sampling distribution of p̂ . assume the size of the population is 25000.

choose the phrase that best describes the shape of the sampling distribution of p̂ below

correct answer was : approx. normal because n≤ 0.05 N and np(1-p) ≥ 10.

Determine the mean of the sampling distribution p̂.

Answer 1

Distribution of $\widehat{p}$ is normal with mean=

Mp=p=0.6

And standard deviation is

p = = po.04 0019 FT 500
