Part 1
a. Construct a
90%
confidence interval. Express the percentages in decimal form.enter your response here<p<enter your response here
(Round to three decimal places as needed.)Part 2
b. Choose the correct answer below.
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
