A medical researcher wishes to try three different techniques to lower cholesterol levels of patients with high cholesterol levels. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, each subject’s cholesterol level is recorded. The researcher wanted to compare the difference in the means. StatCrunch generates a F‐Stat of 11.0948 and a P‐ value of 0.011. What type of hypothesis test is being used? What can be concluded by the results of this test? Use α = 0.05. Group 1 Group 2 Group 3 13 8 4 12 2 12 11 5 4 15 3 8 9 4 9 8 0 6 4. A simple random sample of 320 adults was asked their favorite ice cream flavor. Of the 320 adults surveyed, 58 responded that they preferred mint chocolate chip. Testing the claim that less than 25% of adults prefer mint chocolate chip ice cream in StatCrunch generates a Z‐stat of ‐2.8402 and a P‐value of 0.0023. What type of hypothesis test is being used? What can be concluded at the 05.0 level of significance?
