Chapter 4, Problem AP1.14CPT

To determine

To select the best option from the multiple choice question according to the given question.

Answer to Problem AP1.14CPT

Option (a) is correct.

Explanation of Solution

Based on the box plot,

Option (a) is true because the spread is the distance between the whiskers of the boxplots and we note that these are for both plots about the same.

Option (b) is false as you cannot determine the mean based on a plot.

Option (c) is false because you cannot determine the number of data points from a box plot.

Option (d) is false because the medians are the line below the orange and the yellow parts of the boxes of the boxplots and thus we note that the medians are not equal since the lines are not in the same position.

Option (e) is false because the line in the middle of the box is more to the left of the box than the line in the middle of the box of second plot.

Thus option (a) is the correct option.
