Question 2 of 4 Click For A Question 3 Submit Many diabetics today are using insulin pumps to release small amounts of insulin as needed in order to improve their health. Insulin pumps tend to keep glucose levels in the bloodstream at a more constant level. Suppose that a study is planned to compare Group 1 whose members use insulin pumps to Group 2 whose members use the traditional method of injections. The sample from Group 1 will consist of 20 individuals and the sample from Group 2 will consist of 40 individuals. The samples will be independent and random from populations with equal variances. A researcher wants to determine if there is sufficient evidence to conclude that the glucose levels in the bloodstreams of Group 1 is lower than the glucose levels in the bloodstream of Group 2. Select the correct hypotheses to test. 1. Ho: M - M = 0 HA: M - M2 > 0 2. Ho MM20 HA: M - M = 0 3. Ho: M - M = 0 HA MM2 < 0 4. Ho - MM2 = 0 HA MM20
