The means and mean absolute deviations of the individual times of members on two 4 times 400 meter relay track teams are shown i
Yakvenalex [24]

The correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

<h3>What is mean?</h3>

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.

The difference between the mean times is about 16 times the mean absolute deviation of the data set.

59.32 - 59.1 = 0.22

2.4 - 1.5 = 0.9

0.22 / 0.9 = 0.25

Therefore the correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

step 1

we have

y_1=\left|x-4\right|

y2=1

step 2

The graph in the given problem

step 3

Identify the solution when y1\leq y2

so

\left|x-4\right|\le1

using a graphing tool

The solution is the interval  -----> [3,5]

see the attached figure

All real numbers greater than or equal to 3 and less than or equal to 5

therefore
