# Use the following information to answer the next three exercises: Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. 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. Calculate the following: median = _______

Median $=4$

See the 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

$33333333333333444444444444444444455555\phantom{\rule{0ex}{0ex}}555555566666666677777777777$

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 $4$.
