of people at the picnic?
What effect does it have on the mean?

Answer is below

Step-by-step explanation:

The mean of everyone except the 72-year old grandfather is = 22.18

The mean of everyone including the 72-year old grandfather is = 26.33

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