In a study of the accuracy of fast food drive-through orders, Restaurant A had 213 accurate orders and 68 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 $B:0.226<p<0.305$. What do you conclude? a. Construct a $90\%$ confidence interval. Express the percentages in decimal form. $<p<$ (Round to three decimal places as needed.) b. Choose the correct answer below. A. Since the two confidence intervals overlap, neither restaurant appears to have a significantly different percentage of orders that are not accurate. B. No conclusion can be made because not enough information is given about the confidence interval for Restaurant $B$. C. 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.
