Answer

Explanation:

Step1: Recall range formula

Range = Maximum - Minimum

Step2: Identify max and min from box - plot

The minimum value of the data set represented by the box - plot is 0 and the maximum value is 12. Range = 12 - 0 = 12

Step3: Recall median location in box - plot

The median is the value at the vertical line inside the box. The vertical line inside the box is at 6. So the median is 6.

Step4: Analyze value 5 in box - plot

The box - plot shows the distribution of data in quartiles. The box represents the inter - quartile range (IQR). Since 5 is within the box (the middle 50% of the data), it is possible that some people have 5 cousins.

Answer:

a. 12 b. 6 c. Yes
