Question

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?

Answer 1

67.33. You would first find the total height of people. So 50 would be multiplied by 68, giving you the answer of 3,400. After, you would subtract 82 and 86, giving you 3,232. To get the final answer you would divide the value by 48, since two of them are removed, giving you 67.33.

Answer 2

Your answer for the question above would be 67.33 inches
