Hello,

The new mean is (50*68-82-86)/66=48.969696...≈48.97

The new mean of the heights of the students after the two outliers have been removed to the nearest hundredth is 67.33 inches.

What is the new mean?

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the heights / total students

Sum of the heights = 50 x 68 = 3400 inches

Sum of heights after the outliers are removed = 3400 - 82 - 86 = 3232

New mean = 3232 / 48 = 67.33 inches
