**Answer:**

The mean of the sampling distribution is 0.22 and the standard deviation is 0.0338.

**Step-by-step explanation:**

**Central Limit Theorem:**

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation

**In this question, we have that:**

**a) What are the mean and Standard deviation of the sampling distribution of p-hat**

By the Central Limit Theorem,

Mean:

Standard deviation:

The mean of the sampling distribution is 0.22 and the standard deviation is 0.0338.

Answer: 30 students

Step-by-step explanation:

**Answer:**

20/24

**Step-by-step explanation:**

let the variable be x and x-4

5/6 = x-4/x

cross multiply

5x = 6x - 24

24= x

thus, x is 24 and x-4 is 20

__20/24__
