Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 25 thousand and a standard deviation of 10.6 thousand. what is the probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand?

Step-by-step explanation:

Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.

The standard deviation of the sample means is:

The z value is

We plug in the values to get:

The area to the right of 1.87 is .

The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%

i think it is c, not positive though
