nequals=75

Suppose a simple random sample of size

is obtained from a population whose size is

Upper N equals 15 comma 000N=15,000

and whose population proportion with a specified characteristic is

p equals 0.4 .p=0.4.

Complete parts (a) through (c)

below.

(a) Describe the sampling distribution of

ModifyingAbove p with caretp.

Choose the phrase that best describes the shape of the sampling distribution below.

Approximately normal because

n less than or equals 0.05 Upper Nn≤0.05N

and np left parenthesis 1 minus p right parenthesis greater than or equals 10.np(1−p)≥10.

Not normal because

n less than or equals 0.05 Upper Nn≤0.05N

and np left parenthesis 1 minus p right parenthesis less than 10.np(1−p)<>

Approximately normal because

n less than or equals 0.05 Upper Nn≤0.05N

and np left parenthesis 1 minus p right parenthesis less than 10.np(1−p)<>

Not normal because
