A gardening club measures the weight, in pounds (lb), of each pumpkin in its garden at the end of the growing season.  The histogram shows the weights of the pumpkins.

Complete the statements that describe what happens to the mean and the range of the data when all the pumpkins in the 4- to 6-pound category are REMOVED.

The MEAN of the data will​ (a)   , and the RANGE of the data will​ (b)   .

• INCREASE

• DECREASE

• REMAIN THE SAME

Answer explanation

The pumpkins in the 4-6 pound category pull down the mean (average) of the pumpkin weights, so REMOVING them causes the MEAN (AVERAGE) to INCREASE.

The range is 4 to 21, or 17, with the 4-6 pound pumpkins included. When they are removed, the range is 10 to 21, or 11. So REMOVING them causes the RANGE to DECREASE.

• m = 8, n = 10

• m = 1, n = 1

• m = 3, n = 6

• m = 6, n = 3
