10. A warden is interested in the effectiveness of two different violence reduction programs to reduce violent interactions in her prison. To test for differences, the warden randomizes two groups implementing one program to each group. The amount of violent interactions per inmate is presented below. Using α = .05, perform an independent sample t-test of significance. Then answer the questions below. Show all steps of the calculations in Excel.

show all work. say a researcher is interested in testing the effectiveness of a new stress reduction method. She thinks, or predicts based on previous research, that the new method should reduce stress. one randonmly selected person (our subject) is trained in this method and his stress is measured (low values mean low stress). It is known that stress level of people in the general population has a mean of 40 and a standard deviation of 10. the score of...

Medical researchers interested in determining the relative effectiveness of two different drug treatments on people with a chronic mental illness established two independent test groups. The first group consisted of 14 people with the illness, and the second group consisted of 13 people with the illness. The first group received treatment 1 and had a mean time until remission of 172 days, with a standard deviation of 6 days. The second group received treatment and had a mean time until...

21.) A ski insurance company was conducting research and was interested in the pulse rate of skiers. One scientist from the company wanted to know if skiing would lead to a reduction in an individual's pulse rate. In order to test this hypothesis, the scientist found 8 non-skiers who agreed to being a one month long all paid for skiing program. At the end of the month their pulse rates were determined and compared using earlier values throughout the tests...

In a cognitive psychology experiment, the researcher is interested in whether encoding condition has a significant effect on memory for a list of words. She recruits 32 subjects to participate in the experiment. Each recruited subject is randomly assigned to either encoding condition A or encoding condition B. The researcher would like to leave the hypothesis non-directional without predicting which encoding condition would lead to better memory, and she sets the significance level at α = .05 for a two-tailed...
