Answer 1

Given:

The salesman sold 6 cars on the eight day and redraws the box and whisker plot

Recall that the box and whisker plot is drawn using the data as shown below:

Initially, we have:

lower extreme = 8

upper extreme = 17

median = 12

When 6 is added to the data pool, we now have:

lower extreme = 6

upper extreme = 17

lower quartile would reduce

the median would decrease

the value of the interquartile would increase because the lower quartile is smaller

Hence, the correct options are:

Option A

Option B
