In a study of the accuracy of fast food drive-through orders, Burger King had 264 accurate orders and 54 that were not accurate (based on data from QSR magazine).
a. Construct a 99% confidence interval estimate of the percentage of orders that are not accurate.
b. Compare the result from part (a) to this 99% confidence interval for the percentage of orders that are not accurate at Wendy's: 6.2% < p < 15.9%. What do you conclude?
