Answer:
84.9%
Step-by-step explanation:
First we need to calculate the total number of people. Total number of people will be the sum of all the given frequencies of all classes. There are 9 classes in total that are shown on the histogram
So,
Total number of people = 40 + 40 + 35 + 35 + 25 + 25 + 25 + 25 + 15 = 265
Now we need the number of people who took less than 40 seconds. This will be equal to sum of all frequencies below the time 40 seconds. i.e.
Number of people who took less than 40 seconds = 40 + 40 + 35 + 35 + 25 + 25 + 25 = 225
Formula to calculate percentage is:
So, percentage of people who took less than 40 seconds =
Thus, 84.9% of people took less than 40 seconds to complete the task.
