The following Normal probability plot shows the distribution of points scored for the 551 players in a single NBA season.

If the distribution of points was displayed in a histogram, what would be the best

description of the histogram’s shape?

a. Approximately Normal

b. Symmetric but not approximately Normal

c. Skewed left

d. Skewed right

e. Cannot be determined

Short Answer

Expert verified

The correct option is (d) Skewed right.

Step by step solution

01

Given information

The figure is:

02

Explanation

The data points in the provided image are not following a linear trend, and there is curvature in the accompanying normal probability plot, indicating that the distribution is not normally distributed. In addition, the data points are on the figure's right side. As a result, the supplied distribution could be regarded to be biased to the right.

Thus, the correct option is (d).

Flight times An airline flies the same route at the same time each day. The flight time varies according to a Normal distribution with unknown mean and standard deviation. On 15% of days, the flight takes more than an hour. On 3% of days, the flight lasts 75 minutes or more. Use this information to determine the mean and standard deviation of the flight time distribution.
