The high temperatures for the week were 87, 82, 100, 83, and 88. What is the mean of the temperatures without the outlier

The outliers 100, so we won't include that in the calculation as requested by the question.

Mean is average. Average is calculated by adding quantities together and then dividing the total by the number of quantities.

(87 + 82 + 83 + 88)/4 = 85

Hope this helps!
