![In a study of the accuracy of fast food drive-through orders, Restaurant A had 268 accurate orders and 74 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: \(0.195 < p < 0.269\). What do you conclude?
**a.** Construct a 90% confidence interval. Express the percentages in decimal form.
\[
\boxed{\ \ \ } < p < \boxed{\ \ \ }
\]
