plot labeled Class A. The number line goes from 5 to 14. The whiskers range from 6.5 to 12.5 and the box ranges from 7.5 to 11. A line divides the box at 9. A box-and-whisker plot labeled Class B. The number line goes from 5 to 14. The whiskers range from 6 to 12 and the box ranges from 7.2 to 9. A line divides the box at 8.2. Which class had the higher median score? Which class, as a whole, scored better on the test? a. Class B had the higher median score. Class A scored better on the test. b. Class B had the higher median score. Class B scored better on the test. c. Class A had the higher median score. Class A scored better on the test. d. Class A had the higher median score. Class B scored better on the test.

Korey kept track of the number of miles he ran each week for five weeks. The median number of miles he ran during the five weeks
ivolga24 [154]

Options:

A. 18, 20, 20, 22, 25

B. 20, 20, 20, 25, 25

C. 16, 19, 21, 22, 22

D. 20, 20, 21, 22, 22

Answer:

A. 18, 20, 20, 22, 25

Step-by-step explanation:

Required

Which list has a mean of 21 and median of 20

Each of the list have 5 numbers and they've all been sorted.

The median is the number at the 3rd position (i.e. the middle number)

So, list C and D are out because they do not have a median of 20.

Next, calculate the mean of lists A and B

\bar x = \frac{\sum x}{n}

A. 18, 20, 20, 22, 25

\bar x = \frac{18 + 20 + 20 + 22 + 25}{5}

\bar x = \frac{105}{5}

\bar x = 21

B. 20, 20, 20, 25, 25

 \bar x = \frac{20 + 20 + 20 + 25 + 25}{5}

\bar x = \frac{110}{5}

\bar x = 22

Only list A has a median value of 20 and a mean value of 21
