Answer:

mean- 22

median- 22

range- 14

midrange- 22

Step-by-step explanation:

mean- add up all numbers and divide by amount of numbers- 22

median- number in the middle of a data set- 22

range- greatest value subtracted by least value- 14

midrange- mean of the greatest and least values- 22

The mean if 22, the median is 22, the range is 14 and the midrange is 22.

Given a set of data is 15, 18, 20, 22, 22, 28, 29.

We need to calculate the mean, median, range, and midrange of the number of gallons sold in a week.

What are mean, median, range, and midrange?

The mean is average. Add all the numbers together to find the sum. Then divide the sum by the number of numbers.

Median is a middle number. Arrange the numbers in order from smallest to largest. Find the middle number if there is an odd number.

The midrange is found by putting the numbers in order from smallest to largest. Add the smallest and largest numbers together to find the sum. Divide the sum by 2.

Now, Mean [tex]=\frac{15+20+18+22+22+28+29}{7} =22[/tex]

Now, median of 15, 18, 20, 22, 22, 28, 29 is 22.

Range=Highest observation-Lowest observation=29-15=14.

Midrange [tex]=\frac{15+29}{2}=22[/tex].

Therefore, the mean if 22, the median is 22, the range is 14 and the midrange is 22.
