7.) In a study of the accuracy of fast food drive through orders, based on data from QSR Magazine, Burger King had 264 accurate orders and 54 orders than were not accurate. a.) Construct a 99% confidence interval estimate of the proportion of orders that were not accurate. b.) A similar study of orders at Wendy’s led to a 99% confidence interval estimate of the proportion of orders that were not accurate of: 6.2% < p < 15.9% Comparing that interval with the interval that you constructed, could you definitively conclude that one restaurant has a significantly better rate of accuracy of orders than the other? Why or why not?

Question
7.) In a study of the accuracy of fast food drive through orders, based on data from QSR Magazine,
Burger King had 264 accurate orders and 54 orders than were not accurate.
a.) Construct a 99% confidence
b.) A similar study of orders at Wendy’s led to a 99% confidence interval estimate of the proportion of
orders that were not accurate of: 6.2% < p < 15.9%
Comparing that interval with the interval that you constructed, could you definitively conclude that one
restaurant has a significantly better rate of accuracy of orders than the other? Why or why not?
