a. 20
b. 20.4
c. 21
d. 22

Answer 1

The median number of cars sold this month is 5 cars (c).

Step-by-step explanation:

The median number of cars sold this month can be found by arranging the data in ascending order and finding the middle value. In this case, the data is as follows:

3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 7, 7

There are 21 values in total, so the middle value would be the 11th value. Since the 11th value is 5, the median number of cars sold this month is 5 cars (c).
