Question

A college math professor informs her students that rather than curving final grades, she will replace each students lowest test score with the next to lowest test score, and then re-average the test grades. If Leeza has test scores of 86,92,81,64 and 83, by how many points does her final test average change based on the professor's policy?

Solution

The correct option is B 4

Step 1: Find the original test average:

86+92+81+64+835=81.2

Arrange the marks in order: 64,81,83,86,92

Step 2: Find the average of the tests after replacing the lowest score (64) with the next to lowest score (81): 81+81+83+86+925=84.6

Subtract the original average from the new average: 84.681.2=3.4
