workbook 18
1. 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. x=5.48, SD=22.93
5.48+1.96(22.93) = 170.5992
5.48-1.96(22.93)=80.7136
(80.71,170.60)
2. Which of the following values from Table 1 tells us about variability of the scores in a distribution?
c. 22.57
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. x=39.71, SD=25.46
39.71+1.96(25.46) = 89.6116
39.71-1.96(25.46) = -10.1916
(-10.19, 89.61)
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. x=52.53, SD=30.90
52.53+1.96(30.90) = 113.094
52.53-1.96(30.90) = -8.034
(-8.03, 113.09)
5. Were the body image scores significantly different for women versus men? Provide a rationale for your answer.
Yes, body image scores were significantly higher for women (73.1 ± 17.0) than men (60.2 ± 17.0).
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. x= 57.09, SD=23.72
57.09+2.58(23.72)= 118.2876
57.09-2.58(23.72)= -4.1076
(-4.11, 118.29)
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. X= 65.20, SD=29.79
65.20+2.58(29.79) = 142.0582
65.20-2.58(29.79) = -11.6582
(-11.66, 142.06)
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
5.48+1.96(22.93) = 170.5992
5.48-1.96(22.93)=80.7136
(80.71,170.60)
