The mean would increase after the outlier is removed
Step-by-step explanation:
An outlier in a dataset is a number that differs significantly from the other data in the set.
In this question, 10 is the number that differs significantly from the other data in the set. Thus, it is the outlier.
Mean = sum of the numbers / total number
Mean including the outlier =
(93+ 82 + 10 + 61 + 99 + 89 + 84 + 95 + 75 + 98) / 10 = 78.6
Mean without the outlier =
(93+ 82 + 61 + 99 + 89 + 84 + 95 + 75 + 98) / 9 = 86.2
the mean increased after the outlier was removed
