STEP 1

Assumptions1. The test scores are90,85,74,66,92,83,61,68,80,61,82,58,77,63,88. We need to find the percentage of scores that are less than74

STEP 2

First, we need to count the number of test scores that are less than74.

STEP 3

The scores less than74 are66,61,68,61,58,63. So, there are6 scores less than74.

STEP 4

Next, we need to find the total number of test scores. In this case, there are15 test scores.

STEP 5

To find the percentage of test scores that are less than74, we use the formulaPercentage=Number of scores less than 74Total number of scores×100Percentage = \frac{Number\, of\, scores\, less\, than\,74}{Total\, number\, of\, scores} \times100

STEP 6

Plug in the values for the number of scores less than74 and the total number of scores to calculate the percentage.
Percentage=615×100Percentage = \frac{6}{15} \times100

STEP 7

Calculate the percentage.
Percentage=615×100=40%Percentage = \frac{6}{15} \times100 =40\%So,40% of the test scores are less than74.
