Answer: The range of the tree heights at yard work is greater than the range of the tree heights at the grow station

Step-by-step explanation:

yard works: 7,9,7,12,15

The grow station:9,11,6,12,7

mean of yard works = 7+9+7+12+15/5

=50/5=10

mean of grow station=

9+11+6+12+7 /5

=45/5 =9

The mean of tree heights at yard work is greater than that of grow station.

median(tree at yard work):7,7,9,12,15

median=9

median(tree at grow station)=6,7,9,11,12

median=9

The median of the tree height at yard work is equal to the median of that of tree station.

Range(yard work) = 15 - 7 =8

Range (tree station) =12-6=6

The range of the tree heights at yard work is greater to the tree heights at that of tree station
