Mrs. hall records the heights of 50 students in a spreadsheet. the mean height is 68 inches. after looking at the data again, she realized that two of the 50 observations were outliers that must have been typos, 82 and 86 inches. she deleted these two observations. what is the new mean, rounded to the nearest hundredth?

So, in the situation when she still had the 50 students, the sum of their heights was

50*68=3400 (you can pretend here that all the students are 68 inches tall)

She subtracted the outliners:

3400-82-86=3232, so the new sum is 3232.

She now has to divide it by the number of the students which is now lower by 2: 48

So, 3232/48=67,33

the new mean is 67,33!

The answer is a good luck
