Which t ratio in Table 2 represents the greatest relative or standardized difference between the pretest and 3 months outcomes? Is this t ratio statistically significant?

Use the information in 1 A to determine the area or probability of the following: Round your answer to two decimal places. Which of the following values from Table 1 tells us about variability of the scores in a distribution?

Were the body image scores significantly different for women versus men? Provide a rationale for your answer. What are some limitations of this study that decrease the potential for generalizing the findings to the target population?

The following data represents the remission time in weeks for a random sample of 21 patients using the drug. Use the data to the right to test this claim. Which t ratio in Table 2 represents the greatest relative or standardized difference between the pretest and 3 months outcomes?

Is this t ratio statistically significant? Which t ratio listed in Table 3 represents the smallest relative difference between the pretest and 3 months?

What does this result mean? What are the assumptions for conducting a t-test for dependent groups in a study? Which of these assumptions do you think were met by this study? Compare the 3 months and 6 months t ratios for the variable Exercise from Table 3.

What is your conclusion about the long-term effect of the health-promotion intervention on Exercise in this study? What is the smallest, significant t ratio listed in Table 2?

Why are the larger t ratios more likely to be statistically significant? Did the health-promotion program have a statistically significant effect on Systolic blood pressure BP in this study? Examine the means and standard deviations for Systolic BP at pretest, 3 months completion of the treatmentand 6 months.

What do these results indicate? Are these results clinically important? Is this study design strong or weak? Would you, as a health care provider, implement this intervention at your facility based on the Total Risk Score results?

Is there sufficient evidence to support the claim that women in the different age categories have different mean blood pressure levels? Give reasons for your decision.

HLT V Module 4 Exercise 36 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.

Discuss each aspect of these results. Should the null hypothesis be rejected for the difference between the two groups in change in mobility scores over 12 weeks?

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

Would the null hypothesis be accepted or rejected? Can ANOVA be used to test proposed relationships or predicted correlations between variables in a single group?

If a study had a result of F 2, 4. The researchers state that the sample for their study was 28 women with a diagnosis of OA, and that 18 were randomly assigned to the intervention group and 10 were randomly assigned to the control group.

In your opinion, have the researchers established that guided imagery GI with progressive muscle relaxation PMR reduces pain and decreases mobility difficulties in women with OA? The researchers stated that this was a week longitudinal, randomized clinical trial pilot study with 28 women over 65 years of age with the diagnosis of OA.

What are some of the possible problems or limitations that might occur with this type of study? A Use the Excel Analysis ToolPak to find the linear correlation coefficient for the systolic and diastolic measurements.

B Use the Excel Analysis ToolPak to determine the linear regression equation that uses the systolic pressure to predict the diastolic pressure. C What is the best predicted value for diastolic pressure given that a woman has a systolic level of ?
