In a study of the accuracy of fast food drive-through orders, Restaurant A had 343 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: \(0.141 < p < 0.211\). What do you conclude?

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

- \( \square < p < \square \) (Round to three decimal places as needed.)
