In a study of the accuracy of fast fooddrive-through orders, Restaurant A had 223 accurate orders and 54 that were not accurate.

-Construct a 95% confidence interval estimate of the percentage of orders that are not accurate.

- Compare the results from part(a) to this 95% confidence interval for the percentage of orders that are not accurate at RestaurantB: 0.168

1. Construct a 95% confidence interval. Express the percentages in decimal form.

_________< p <_______ (Round to three decimal places asneeded.)

2. Choose the correct answer below.

A. No conclusion can be made because not enough information is given about the confidence interval for Restaurant B.

B. The lower confidence limit of the interval for Restaurant B is higher than the lower confidence limit of the interval for Restaurant A and the upper confidence limit of the interval for Restaurant B is also higher than the upper confidence limit of the interval for Restaurant A.Therefore, Restaurant B has a significantly higher percentage of orders that are not accurate.

C. Since the two confidence intervalsoverlap, neither restaurant appears to have a significantly different percentage of orders that are not accurate.

D.Since the upper confidence limit of the interval for Restaurant B is higher than both the lower and upper confidence limits of the interval for RestaurantA, this indicates that Restaurant B has a significantly higher percentage of orders that are not accurate.
