here are the test scores for 12 students in mr. ps class. 91, 78, 56, 48, 87, 69, 84, 98, 36, 62, 43, 74. what is the percentage of these test scores that are less than 74?

Explanation:

Step1: Count scores less than 74

The scores less than 74 are 56, 48, 69, 36, 62, 43. There are 6 such scores.

Step2: Calculate the percentage

The formula for percentage is $\frac{\text{Number of scores less than 74}}{\text{Total number of scores}}\times100\%$. Here, the total number of scores is 12. So the percentage is $\frac{6}{12}\times 100\% = 50\%$.

Answer:

50%
