The table shows the names and heights of some of the tallest roller coasters in the United States. (Source: Today.com)

a. Find and interpret (report in context) the mean height of these roller coasters.
b. Find and interpret the standard deviation of the height of these roller coasters.
c. If the Kingda Ka coaster was only 420 feet high, how would this affect the mean and standard deviation you calculated in (a) and (b). Now recalculate the mean and standard deviation using 420 as the height of Kingda Ka. Was your prediction correct?
