Assuming that the distribution is normal for weight relative to the ideal and 99% of the male participants Scored between (–53.68, 64.64), where did 95% of the values for weight relative to the ideal lie?

Round your answer to two decimal places.The z-score corresponding to 95% is 1.96 X=5.48, sd = 22.93The answer is (2. Which of the following values from Table 1 tells us about variability of the scores in a distribution?a) 60.22b) 11.94c) 22.57d) 53.66The answer is c (22.57); standard deviation is a measure of dispersion.3. Assuming that the distribution for General Health Perceptions is normal, 95% of the females’ scores around the mean were between what values? Round your answer to two decimal places.

The answer is 4. Assuming that the distribution of scores for Pain is normal, 95% of the men’s scores around the mean were between what two values? Round your answer to two decimal places.The answer is 5. Were the body image scores significantly different for women versus men? Provide a rationale for your answer.Body image scores which ranged from 0 to a 100 scale were notably higher for women with a mean of (73.1 +/- 16.93) than men with a mean of (60.2 +/- 16.98), as evident on table 1 results (Michael, Stephen, & Machin, 2007). 6. Assuming that the distribution of Mental Health scores for men is normal, where are 99% of the men’s mental health scores around the mean in this distribution?

Round your answer to two decimal places.The z-score corresponding to 95% is 2.576 The answer is 7. Assuming that the distribution of scores for Physical Functioning in women is normal, where are 99% of the women’s scores around the mean in this distribution? Round your answer to two decimal places.The answer is 8. Assuming that the distribution of scores is normal, 99% of HIV-positive body image scores around the mean were between what two values? Round your answer to two decimal places.MaleThe answer is FemaleThe answer is 9.

Assuming that the distribution of scores for Role Functioning is normal, 99% of the men’s scores around the mean were between what values? Round your answer to two decimal places.The answer is 10. What are some of the limitations of this study that decrease the potential for generalizing the findings to the target population?Use of a small sample group to generalize the target population can result to biased findings. Besides, it is very difficult to ascertain that the sample taken is representative.

Moreover, it may be difficult to quantify some facts for instance general health perception. ReferencesMichael, C., Stephen, W., & Machin, D. (2007). Medical statistics : a textbook for the health sciences. Chichester, England: Wiley.
