Question

Jacob recorded the ages of the people at a picnic. The data set is listed below.

Answer 1

Answer:

Answer is below

Step-by-step explanation:

The mean of everyone except the 72-year old grandfather is $\frac{\left(12+12+14+15+16+20+24+28+32+35+36\right)}{11}$ = 22.18

The mean of everyone including the 72-year old grandfather is $\frac{\left(12+12+14+15+16+20+24+28+32+35+36+72\right)}{12}$ = 26.33

Adding in the 72-year old grandfather increases the mean because he is older than everyone else, creating a higher mean.
