The line in the xyxyx, y-plane above represents the relationship between the height h(x)h(x)h, left parenthesis, x, right parent
hesis, in feet, and the base diameter xxx, in feet, for cylindrical Doric columns in ancient Greek architecture. How much greater is the height of a Doric column that has a base diameter of 555 feet than the height of a Doric column that has a base diameter of 222 feet?

To solve this problem, first we have to determine the z statistic. The formula is
where x is the test point which is 8.019, the mean is 8 mph, s is the standard deviation which is 3.813 and n is the number of data which is 1114. Then,
Next, we find the p-value for the particular z. p-value is used in hypothetical test. Using a wind turbine would be the null hypothesis. From the standard normal table found in any statistics book, the p-value for z<0.17 is 0.5675. If the p-value is greater than 0.05, then you do not reject the null hypothesis.
Therefore, the landowner could use a small turbine at the site.
