State which type of average, the mean, median, or mode, would be most appropriate in the situation described. Explain your thinking.An engineer has designed an elevator and wishes to determine the maximum number of people that will be allowed to ride in the elevator at a time. In order to do this, the engineer needs to know the average weight of the people likely to ride in the elevator. Which type of average would be the most useful?
What will be an ideal response?
The mean. The mean takes into account the numerical value of all the weights and thus will allow the engineer to estimate the total weight of a given number of people.
