In a study of the accuracy of fast food drive-through orders, Restaurant A had 282 accurate orders and 57 that were not accurate. a. Construct a 90% confidence interval estimate of the percentage of orders that are not accurate. b. Compare the results from part (a) to this 90% confidence interval for the percentage of orders that are not accurate at Restaurant B: 0.152 <p<0.223. What do you conclude? 135 <p< 202 (Round to three decimal places as needed.) b. Choose the correct answer below. **** O A. Since the two confidence intervals overlap, neither restaurant appears to have a significantly different percentage of orders that are not accurate. OB. 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. OC. 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 Restaurant A, this indicates that Restaurant B has a significantly higher percentage of orders that are not accurate. O D. No conclusion can be made because not enough information is given about the confidence interval for Restaurant B.
