Please answer part D.

Solution

The distribution is right skewed as the maximum of the data lies on the left side of the central position. And it is unimodal because it has a unique mode value. The frequency increases initially, goes to a peak value and then decreases, so it has a unique mode (central value) with maximum frequency.

The center and spread of a data can be best estimated using the mean and the variance of the data respectively.

And, it is given that Mean is = 5887.18

And Standard Deviation = 392.57
