The table shows the weight of eight different bear species at a zoo. If the weight of the polar bear is removed, which statement is true of the data set?

• The mean decreases more than the median because the polar bear is a high outlier.

• The mean decreases less than the median because the polar bear is a high outlier.

• The mean decreases more than the median because the high value balances the low value.

• The mean decreases less than the median because the high value balances the low value.

• 20 square units

• 30 square units

• 35 square units

• 45 square units
