groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F (1, 22) = 9.619,

p = 0.005. Discuss each aspect of these results.

The researchers were able to conclude that the finding was significant because the Statistical value (F) had a p-value of less than .05, which is the cut-off point for significance. Consequently, they can conclude that there is a significant difference between the control and treatment groups over time.

State the null hypothesis for the Baird and Sands (2004) study that focuses on the effect of the GI with PMR treatment on patients' mobility level. Should the null hypothesis be rejected for the difference between the two groups in change in mobility scores over 12 weeks? Provide a rationale for your answer.

The null hypothesis is that there are no differences in mean scores. The p value for the findings is less than .05, meaning that the null hypothesis can be rejected, and that the alternative hypothesis, that there are significant differences between difficulty and mobility scores, can be accepted.

3. The researchers stated that the participants in the intervention group reported a reduction in mobility difficulty at week 12. Was this result statistically significant, and if so at what probability?

Yes, this result was statistically significant, with a probability score of less than .001.

4. If the researchers had set the level of significance or ? = 0.01, would the results of p = 0.001 still be statistically significant? Provide a rationale for your answer.

Yes, the result would still be statistically significant because .001 is less than .01.

5. If F (3, 60) = 4.13, p = 0.04, and ? = 0.01, is the result statistically significant? Provide a rationale for your answer. Would the null hypothesis be accepted or rejected?

There is no statistical significance here because .04 is greater than .01. If the alpha was set to .05, then the finding would be significant. In this case, however, the null hypothesis would fail to be rejected (it is not proper to say that the null hypothesis was accepted, simply that one was unable.....
