I am struggling with statistics! please help me solve this problem

Suppose a simple random sample of size nequals

=75

75 is obtained from a population whose size is Upper N equals 10 comma 000

N=10,000 and whose population proportion with a specified characteristic is p equals 0.2 .

p=0.2. Complete parts (a) through(c) below.

(a) Describe the sampling distribution of ModifyingAbove p with caret

p.

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

A.

Approximately normal because n less than or equals 0.05 Upper N

n0.05N and np left parenthesis 1 minus p right parenthesis less than 10.

np(1p)<10.

B.

Approximately normal because n less than or equals 0.05 Upper N

n0.05N and np left parenthesis 1 minus p right parenthesis greater than or equals 10.

np(1p)10.

C.

Not normal because n less than or equals 0.05 Upper N

n0.05N and np left parenthesis 1 minus p right parenthesis greater than or equals 10.

np(1p)10.

D.

Not normal because n less than or equals 0.05 Upper N

n0.05N and np left parenthesis 1 minus p right parenthesis less than 10.

np(1p)<10.
