  Statistics Through Applications, Chapter 2.1, Problem 2.7E

By seeing the dot plot it is clearly show that it is right skewed because highest dot on the left side and the mode is 0 because of highest number of dot on the 0 and the spread of the data is between 0 and 7 which is looking forth.

(b)

To determine

To Explain: the distribution of the variable and shape, centre and spread.

(b)

Expert Solution
Check Mark

Explanation of Solution

By seeing the dot plot, most of the data points are on the left side and little dot plots on the right side so the distribution is right skewed. Maximum dot plots on 0 so mode is 0. The center lies at 1 and the minimum and maximum values are 0 and 7 respectively so the data spread between 0 and 7. Inter quartile range is 3 and 1st quartile and 3rd quartile are 0 and 3 respectively.
