In a study of the accuracy of fast food drive-through orders, Restaurant A had 242 accurate orders and 61 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: 0.183
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

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: 0.183 <p<0.267. 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. No conclusion can be made because not enough information is given about the confidence interval for Restaurant B.
O B. 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 inter
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
accurate.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0eb37d92-f7b6-431f-b5c5-59d6202076f2%2Fbb72bd14-6526-4243-922f-705876d51fc7%2Fzirzwll_processed.jpeg&w=3840&q=75)

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 C. Since the two confidence intervals overlap, neither restaurant appears to have a signifiĉantly 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0eb37d92-f7b6-431f-b5c5-59d6202076f2%2Fbb72bd14-6526-4243-922f-705876d51fc7%2Fjrkvuw_processed.jpeg&w=3840&q=75)
