Answer:
Step-by-step explanation:
The mean which is also known as the average is determined by dividing the sum of the weight of the packages by the total number of packages. From the information given,
Mean = (26 + 18 + 58 + 22 + 54 + 50)/6 = 38
If you include a package that weighs 66 ounces, the new mean would be
New mean = (26 + 18 + 58 + 22 + 54 + 50 + 66)/7 = 42
For the median, we would rearrange the weights in ascending order. It becomes
18, 22, 26, 50, 54, 58
Median = (26 + 50)/2 = 38
By adding the new weight, it becomes
18, 22, 26, 50, 54, 58, 66
New median = 50
It can be seen that both the median increased by more. It increased by 12 while the mean increased by 4
