We already know answer is C. Suppose a simple random sample of size n=50 is obtained from a population whose size is N=20,000 and whose population proportion with a specified characteristic is p=0.6. Complete parts ​(a) through​ (c) below.
​(a) Describe the sampling distribution of p.
Choose the phrase that best describes the shape of the sampling distribution below.
A.
Not normal because n≤0.05N and np(1−p)≥10.
B.
Not normal because n≤0.05N and np(1−p)<10.
C.
Approximately normal because n≤0.05N and np(1−p)≥10.
Your answer is correct. D.
Approximately normal because n≤0.05N and np(1−p)<10.
Determine the mean of the sampling distribution of p.
μp=? ​(Round to one decimal place as​ needed.)
