Suppose a simple random sample of size

n=125

is obtained from a population whose size is

N=10,000

and whose population proportion with a specified characteristic is

p=0.4.

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.

Approximately normal because

n≤0.05N

and np(1−p)<10.

C.

Not normal because

n≤0.05N

and np(1−p)<10.

D.

Approximately normal because

n≤0.05N

and np(1−p)≥10.

Determine the mean of the sampling distribution of

p.

μp=nothing

​(Round to one decimal place as​ needed.)

Determine the standard deviation of the sampling distribution of

p.

σp=nothing

​(Round to six decimal places as​ needed.)

​(b) What is the probability of obtaining

x=55

or more individuals with the​ characteristic? That​ is, what is

​P(p≥0.44​)?

​P(p≥0.44​)=nothing

​(Round to four decimal places as​ needed.)

​(c) What is the probability of obtaining

x=40

or fewer individuals with the​ characteristic?

​P(p≤0.32​)=nothing

​(Round to four decimal places as​ needed.)
