A=W times L

A=145/4

L=35/4

W=145/4/35/4

Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 25 thousan
ohaa [14]

Answer:

P(\bar X\:>27.8\:thousand)=3.07\%

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:

\sigma_X=\frac{\sigma}{\sqrt{n} }

\implies \sigma_X=\frac{10.6}{\sqrt{50} }=1.4991

The z value is z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n}} }

We plug in the values to get:

z=\frac{27.8-25}{1.4991}=\frac{2.8}{1.4991}=1.87

The area to the right of 1.87 is 1-0.96926=0.03074.

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%
