Question

An insurance company crashed four cars of the same model at 5 miles per hour. The costs of repair for each of the four crashes were ​$436​, ​$403​, ​$479​, and ​$249 . Compute the​ mean, median, and mode cost of repair. Compute the mean cost of repair. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice. A. The mean cost of repair is ​$ nothing. ​(Round to the nearest cent as​ needed.) B. The mean does not exist.

Answer 1

Answer:

Data :  ​$436​, ​$403​, ​$479​, and ​$249 .

$Mean = \frac{\text{Sum of all observations }}{\text{total no. of observations}}$

$Mean = \frac{436​+403​+479​+249}{4}$

$Mean = 391.75$

No. of terms n = 4 (even)

Median = $\frac{\frac{n}{2}th +(\frac{n}{2} +1)th}{2}$

Median = $\frac{\frac{4}{2}th +(\frac{4}{2} +1)th}{2}$

Median = $\frac{2nd +(3)rd}{2}$

Median = $\frac{403+479}{2}$

Median = $441$

Mode is the value repeating the more no. of times

So, there is no mode.

Hence Mean is 391.75 , Median is 441 and no mode.
