Q. How might an extreme value in the sample data set affect the value of the mean
a. an extreme value cannot affect the mean if it is close to the mean
b. all values are treated equally when determining the mean, so an extreme value cannot affect it
c. since all values are summed, any extreme value can influence the mean to a large extent
