3. A study was conducted to compare automobile gasoline mileage for three formulations of gasoline. Four automobiles, all of the same make and model, were used, and each formulation was tested in each automobile, thuseliminating automobile-to-automobile variability. The data (in miles per gallon) follow.DataAutomobileFormulation1234A25.727.027.326.1В27.228.127.927.726.127.526.827.8a. Do the data provide sufficient evidence to indicate a difference in mean mileage per gallon for the three gasoline formulations?b. Is there evidence of a difference in mean mileage for the four automobiles?

Introduction: We need to perform two tests- one to check if the mean mileage per gallon differs for…

A researcher is interested in the relationship between age and golf performance. The researcher claims that golf performance improves with age, that is, as one gets older, his or her golf scores decrease. [In golf, a low score represents better performance; a higher score represents worse performance.] The researcher randomly selects a group of eight golfers at the local golf course and records their ages and their most recent golf score. The data that were collected are presented below: Golfer's Name Diego Tiger Bogart Marilyn Jennifer Mitch Bubba Amber Age (years) Variable 1 23 14 38 43 49 36 72 Golf Score Variable 2 92 112 77 84 81 72 79 86 Which of the following are the correct statements of the null and alternate hypotheses, Ho and HA?
