Question

1. based on the box plot below, which statement is not true? age of service team members a. the oldest team member is 24. b. the median age is 22. c. fifty percent of the members are between 22 and 24. d. less than 25% of the members are 20 or younger.

Explanation:

Step1: Recall box - plot properties

In a box - plot, the end of the right - most whisker represents the maximum value.

Step2: Analyze option A

The right - most whisker extends to 26, so the oldest team member is 26, not 24. Option A is false.

Step3: Analyze option B

The line inside the box represents the median. Here, the line is at 22, so the median age is 22. Option B is true.

Step4: Analyze option C

The box represents the inter - quartile range (IQR), which contains 50% of the data. The box goes from 22 to 24, so 50% of the members are between 22 and 24. Option C is true.

Step5: Analyze option D

The left - most whisker and the part of the box to the left of the median represent the lower 50% of the data. The value 20 is the first quartile (Q1), so 25% of the members are 20 or younger. Option D is true.

Answer:

A. The oldest team member is 24.
