Delta has a new jumbo 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.
Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent study, 82 patients with Type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that less than 75% of those with diabetes who undergo this surgery will recover from diabetes?

A report in LTO stated that the average age of taxis in the Philippines is 9 years. An operations manager of a large taxi company selects a sample of 40 taxis and finds the average age of the taxis is 8.2 years. The σ of the population is 2.3 years. At ? = 0.05, can it be concluded that the average age of the taxis in his company is less than the national average?

To check the activation level of data scientists, a population of data scientists was asked to play games for a fixed time duration and their brain activation levels were tested. The outcome of this research stated that playing the mobile games for a fixed time duration improved the concentration level with an average brain activation level of 100 units. If a sample of 12 data scientists were tested for the same experiment, the brain activation levels were reported as follows: 105, 90, 91, 96, 96, 91, 100, 105, 99, 107, 103 and 92 a. Does this data suggest that the population mean reading for the brain activation level under the given conditions differs from 100?

A poll conducted asked a random sample of 1342 adults in the United States how much confidence they had in banks and other financial institutions. A total of 143 adults said that they had a great deal of confidence. An economist claims that less than 14% of U.S, adults have a great deal of confidence in banks, Can you conclude that the economist's claim is true?

A recent study examined the effects of carbon monoxide exposure on a group of construction workers. The following table presents the numbers of workers who reported various symptoms, along with the shift (morning, evening, or night) that they worked. Morning Shift Evening Shift Night Shift Influenza 19 12 17 Headache 15 33 6 Weakness 12 14 7 Shortness of Breath 6 10 7 Send data to Excel Test the hypothesis of independence. Use the =α0.10 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude? H0: The shift and reported symptoms are/are not independent. H1: The shift and reported symptoms are/are not independent. This hypothesis test is a left tailed/right tailed/two tailed test.

A new chemotherapy drug is released to treat leukemia and researchers suspect that the drug may have fewer side effects than the most commonly used drug to treat leukemia. The two drugs have equivalent efficacy. In order to determine if a larger study should be conducted to look into the prevalence of side effects for the two drugs, set up a Mann-Whitney Utest at the alpha equals .05 level and interpret its results.
