HLT-362V Applied Statistics for Health Care Professionals Exercise 36 in Statistics for Health Care Research: A Practical Workbook. 1. The researchers found a significant difference between the two 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. There is a significant difference between the control and treatment group with an F value at 5% level. The p value of 0.005 is less than 0.05. The null hypothesis would then be rejected due to this factor. 2. 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 the woman receiving guided imagery show no greater improvement in their pain scores than the control group after 12 weeks. The study results indicated significant improvement in mobility scores of women who received treatment (F(1, 22)= 9.619, p = 0.005). The null hypothesis would be rejected. 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? The intervention group reported a reduction in mobility difficulty at week 12 was statistically significant at p < 0.001 probability. 4. If the researchers had set the level of significance or α = 0.01, would the results of p = 0.001 still be statistically significant? Provide a rationale for your answer. If the researches had set the level of significance or α = 0.01, the results of p = 0.001 would be significant due to the
