Question

Here are the heights (in inches) of 15 students in a seminar.

77, 74, 68, 65, 78, 73, 61, 66, 70, 62, 72, 60, 69, 64, 75
What is the percentage of these students who are shorter than 67 inches?

Answer 1

The percentage of these students who are shorter than 67 inches is 40%

What is the percentage of these students who are shorter than 67 inches?

From the question, we have the following parameters that can be used in our computation:

77, 74, 68, 65, 78, 73, 61, 66, 70, 62, 72, 60, 69, 64, 75

Where, we have

Total = 15

Height less than 67 = 6

So, we have the percentage to be

percentage = 6/15 * 100%

Evaluate

percentage = 40%

Hence, the percentage is 40%

Answer 2

There are 15 students in total and 6 of them are shorter than 67 inches. So 6 divided by 15 would be 0.4 or 40%.
