Question

A polling company took 5 polls in the week before an election. It showed that a mayoral candidate would get 66%, 56%, 55%, and 63% of the voters. That candidate received 64% of the total votes during the actual election. Find the percent error in the average of the company's polling results, to the nearest tenth of a percent. Show your work.

Answer 1

average = (1/4)(66+56+55+63)
= 60

percent error = 100 (64 - 60)/64
= 6.25 %
