In a study of the accuracy of fast food drive-through orders, Restaurant A had 323 accurate orders and 70 that were not accurate.a. **Construct a 90% confidence interval estimate of the percentage of orders that are not accurate.**- Use decimal form for percentages, rounded to three decimal places.b. **Compare the results from part (a) to this 90% confidence interval for Restaurant B: 0.166 < p < 0.222. What do you conclude?**- **Choices to Consider:** - **A.** The upper confidence limit of the interval for Restaurant B is higher than both the lower and upper limits of the interval for Restaurant A. This indicates Restaurant B has a significantly higher percentage of inaccurate orders. - **B.** No conclusion can be made as not enough information is given about the confidence interval for Restaurant B. - **C.** Since the two confidence intervals overlap, neither restaurant appears to have a significantly different percentage of inaccurate orders. - **D.** The lower confidence limit of the interval for Restaurant B is higher than the lower confidence limit for Restaurant A, and the upper limit for Restaurant B is also higher than the upper limit for Restaurant A. Therefore, Restaurant B has a significantly higher percentage of inaccurate orders.
