Step by Step Solution

Step 1: Given information

From sixty-five car salespersons, fourteen people answered that they generally sell three cars; nineteen generally sell four cars; twelve generally sell five cars; nine generally sell six cars; eleven generally sell seven cars in one week.

Step 2: Explanation

According to the given information, the data is

3 3 3 3 3 3 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 5 5 5 5 55 5 5 5 5 5 5 6 6 6 6 6 6 6 6 6 7 7 7 7 7 7 7 7 7 7 7

Here we divide all this 65 data in 100 scale. We asked to find the second quartile (median) of the number of cars sold which is the first 50% of the data. Hence we get 50% of the data from first is 4.
