Question 5 (4 points)
Bobo's Bad Burgers fast food claims you will be in and out in 5 minutes. To test this claim, time
in minutes from entering Bobo's to receiving the order was secretly recorded. The results are
documented in DATA. At a 95% confidence level, does the confidence interval support Bobo's
claim?
The confidence limits (4.77,6.58) support the claim of 5 minutes. 5 falls inbetween the
confidence limits. Bobo's performance meets the expectation.
The confidence limits (6.79,8.56) reject the claim of 5 minutes. 5 is less than the lower
confidence limit. Audit of Bobo's procedures and employees is recommended.
The confidence limits (1.62,3.21) reject the claim of 5 minutes. 5 is greater than the upper
confidence limit. Performance at Bobo's is incredible.
The confidence limits (2.77, 4.54) reject the claim of 5 minutes. 5 is greater than the
upper confidence limit. Bobo's performance is exemplary.
None of the answers match my calculations.
