• I need help with my last question please. and I believe my answers are correct 1-3? The scenario is attached. Thank you!

Determine what question(s) the researchers are trying to answer by doing this research.

The researcher wants to determine the effects of exercise levels on stress?

Determine the hypotheses being tested. Is the alternative hypothesis directional or nondirectional?

The hypothesis being tested is whether the level of stress decreases as the level of exercise increases?. The hypothesis is directional?

Identify the independent variable(s), the dependent variable, and the specific type of ANOVA used.

The independent variable is the level of exercise?; the dependent variable is the levels of stress?and the type of ANOVA is what I really really need help with!!

Researchers wanted to determine the effects of exercise on stress. They divided a random sample into groups, with each group having a specified level of exercise. A pretest of stress levels was given to all participants to establish a baseline. One group had strenuous exercise, another had moderate exercise, and another was the control group which had no exercise. After the exercise period, a posttest was given to measure the stress level. The scores for comparison were calculated by subtracting the baseline stress measurement from the final stress measurement.

Here is the ANOVA table with the results:
