graphing calculator

Explanation:

To determine if eight people can safely use an elevator with a 1500 - pound maximum capacity, we need to know the total weight of the people. The mean weight of the people would be useful as if we multiply the mean weight by 8 (number of people), we can compare it to 1500 pounds. Inter - quartile range, mode, and median do not give us a measure that can be directly used to find the total weight of the 8 people for this comparison.

Answer:

mean
