![In a study of the accuracy of fast food drive-through orders, Restaurant A had 216 accurate orders and 66 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: 0.214 < p < 0.298. What do you conclude?**
a. **Construct a 90% confidence interval. Express the percentages in decimal form.**
\[ \_\_ < p < \_\_ \]
*(Round to three decimal places as needed.)*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F12540699-3e1e-4e0f-bf0a-577c3791a7bd%2Fa3efa9b4-09be-4df5-9c0d-88f029a02332%2F2q0f08f_processed.png&w=3840&q=75)
