(b) Determine if the mean or the median would be a better measure of center for this distrubution. If the mean is​ better, calculate the value. If the median is​ better, give the midpoint of the interval that contains it.

Select the correct choice below and fill in the answer box to complete your choice.

A.

The median is a better measure of center for this distribution.

The midpoint of the interval that contains the median is

​$nothing.

​(Round to the nearest integer as​ needed.)

B.

The mean is a better measure of center for this distribution.

The value of the mean is

​$nothing.

​(Round to the nearest integer as​ needed.)

Answer 1

since data appear to be left skewed
