An insurance institute conducted tests with crashes of new cars traveling at 6 mi/h. the total cost of the damages was found for a simple random sample of the tested cars and listed below. find the a)mean, b)median c) mode, d) midrange for the given sample data. do the different measures of center differ very much? $7,431 $4,859 $8,961 $6,372 $4,363

Mean = $6,397.2

Median = $6,372  

Midrange = $6,662

Step-by-step explanation:

We are given the following data:

$7,431, $4,859, $8,961, $6,372, $4,363

Formula:

Mode is the most frequent observation in the dataset.

Mean =

Median:

Data in increasing order: 4363, 4859, 6372, 7431, 8961

Median = = 6372

Mode: All values appeared once.

Midrange =

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
