Question

Transcribed Image Text:In a study of the accuracy of fast food drive-through orders, Restaurant A had 335 accurate orders and 65 that were not accurate
a. Construct a 95% confidence interval estimate of the percentage of orders that are not accurate.
b. Compare the results from part (a) to this 95% confidence interval for the percentage of orders that are not accurate at Restaurant B: 0.148 <p<0217. What do you conclude?
a. Construct a 95% confidence interval Express the percentages in decimal form.
<p<(Round to three decimal places as needed)
b. Choose the correct answer below.
O A. 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.
O B. No conclusion can be made because not enough information is given about the confidence interval for Restaurant B.
O C. Since the two confidence intervals overlap, neither restaurant appears to have a significantly different percentage of orders that are not accurate
O 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 Restaurant A, this indicates that Restaurant B has a significantly higher
percentage of orders that are not accurate.
