![In a study of the accuracy of fast food drive-through orders, Restaurant A had 239 accurate orders and 60 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: 0.181 <p<0.281. What do you conclude?
a. Construct a 90% confidence interval. Express the percentages in decimal form.
O<p<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. No conclusion can be made because not enough information is given about the confidence interval for Restaurant B.
OC. Since the upper confidence limit of the interval for Restaurant Bis 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.
OD. The lower confidence limit of the interval for Restaurant Bis higher than the lower confidence limit of the interval for Restaurant A and the upper confidence limit of the interval for Restaurant Bis also higher than the upper confidence limit of
