Hypothesis Testing

Explain Excel

Delta has a newjumbo jet they believe will decrease the flight time from Newark to London Heathrow. To be faster than its competitors, the mean must be less than 6 h 50 minutes (or 410 minutes). Because of costs, the agency monitoring the flight times only requires that eight trials be run. The results (in minutes) are given in the spreadsheet. If the FAA requires that the agency be 90% confident of its findings (so an alpha level of 0.10), what should the agency report? Conduct an appropriate hypothesis test using Excel. Assume the population distribution is approximately normal. For your second post, either provide quality feedback to a classmate, or find CORRESPONDING interval to verify that your conclusion is the same as that of your test and tell what that interval means in context. A B C 1 Flight # Flying Time 2 1 385 3 388 4 405 5 362 6 412 7 444 8 396 9 8 402 10 11
