Decide which Wilcoxon test (i.e. the Wilcoxon signed-ranks test or Wilcoxon Rank Sums test) should be used. Then test the claim. Exercise 5. Fuel octane. A researcher wants to know if the octane level in gasoline affects car mileage. 12 randomly selected cars are tested. 5 gallons of 87-octane gas is put in the tank and then the car is run until it runs out of gas. The same cars are then tested in the same way, except that 5...
Problem 7- Wilcoxon Signed-Rank test A sample of 10 men was used in a study to test the effects of a relaxant on the time required to fall asleep. Data for 10 subjects showing the number of minutes required to fall asleep with and without the relaxant follows. Calculate the test-statistic (create all necessary columns to the right of the table to show all the working). If the level of significance is 0.05 and the calculated p-value for the test...
