Question

The number of licensed drivers in four samples taken from a population of students are shown in the table below. Which of the following choices is most likely closest to the percentage of students in the population who are licensed drivers

Answer 1

Answer:

A. 24%

Step-by-step explanation:

The number of licensed drivers in four samples taken from a population of students are given by:

Sample Size      Number of Licensed Drivers

     25                                   7

     50                                  8

     75                                  18

     100                                 25

The number who are licensed drivers is the ratio of the sum of the total licensed drivers of each sample divided by the total number of sample.

Assume Licensed Drivers is x

Hence, we get:

x = 7 + 8 + 18 +20 / 4

x = 53 / 4

x = 13.25

which is closest to 18

Hence, the answer is:  18 / 75 x 100 = 24%
