Scenario 2. A researcher is interested in examining how a new exercise program aimed at body positivity can influence teenagers’ self-esteem. She randomly assigns teenagers to either engage in the new exercise program for 8 weeks (the experimental group) or to a control group that does not do the program and then compares their self-esteem.

H0: self esteem in the experimental group
self esteem in the control group
H0: self esteem in the experimental group < self esteem in the control group
H0: rxy = 0
Question 6
What is the alternative hypothesis for scenario 2?
Group of answer choices
H1: self esteem in the experimental group > self esteem in the control group
H1: self esteem in the experimental group < self esteem in the control group
H1: self esteem in the experimental group
self esteem in the control group
H1: self esteem in the experimental group = self esteem in the control group
H1: µ1(experimental group)
µ2(control group 1)
µ3(control group 2)
H1: rxy = 0

Happiness
Time spent on zoom
The participants’ workload
The type of job they have
Scenario 4. A researcher wants to explore whether stress increases after experiencing sleep deprivation. She measures participants stress levels before and after staying up for one night.

Scenario 5. A researcher is interested in examining how different employee-morale boosting activities can influence employee job satisfaction. She randomly assigns different companies to provide one of three possible activities: an employee appreciation lunch, free coffee every Wednesday for a month, or a 20-minute extended lunch break every Friday for a month an then compares employee satisfaction rates between the three companies.

Question 21
Come up with your own study idea, just like the scenarios you see in the questions above. Explain the study (just like in scenarios above), and then tell me the following information for your study. Make sure this is your own original study idea!
IV:
DV:
Null Hypothesis:
Alternative Hypothesis:
Type of Analysis you would use to test the hypothesis in your study:
p
0 words
Question 22
Now, pretend you actually ran the study you came up with. Make up the results (the test statistic values, means and SDs), and write up the results as you would see them in an APA style research paper. Note, you do not actually have to do any calculations here! You just need to make up the means and sds for each group, the test statistic value, and the p value and write out the results. You can use the answers to the write up questions on the previous 4 assignments as a template for this!
