Relevant Study Results
“The sample consisted of 23 men with a mean age of 42.2 years (SD = 8.2), length of time since
diagnosis with HIV was 9.2 years (SD = 5.3); and 17 women with a mean age of 36.8 years (SD = 5.2), and length of time since diagnosis with HIV was 7.2 years (SD = 4.8). For men, 23 were HIV-positive and 9 had a diagnosis of AIDS; and for women, 17 were HIV positive, and 5 had a diagnosis of AIDS. There was no significant difference in demographic characteristics of the sample by age, gender, HIV disease status, and time living with HIV.
Participants reported a net increase in weight from 3 months prior (M = 2.4 lb, SD = 12.9 lb) and
12 months prior (M = 10.9 lb, SD = 19.1 lb) and that their weight was greater than their ideal weight (M = 9.2 lb, SD = 22.9 lb). SDs for the data indicated a wide range on weight at both 3 and 12 months before participation in the study.
Body image scores (0–100 scale) were significantly (F(1, 37) = 5.41, p =.03) higher for women
(73.1 ± 17.0) than men (60.2 ± 17.0). Although HIV-positive participants had slightly higher body image scores (M = 68.0, SD = 17.0) compared with participants with AIDS (M = 60.5, SD = 18.8), there was no significant difference (F(1, 37) = 1.56, p =.22) in body image scores between [those with HIV and AIDS]. There was a weak, but significant, inverse association between body image score and weight changes from 3 months prior (r = −.30, p =.04). Body image and weight scores are summarized in Table 1” (Corless et al., 2004, p. 294).

“A summary of quality-of-life scores for men and women is shown in Table 2. The scales
of the MOS-HIV Quality of Life instrument include General Health Perceptions, Physical
Functioning, Role Functioning, Social Functioning, Cognitive Functioning, Pain, Mental Health,
Vitality, Health Distress, Quality of Life, and Heath Transition. There were no significant differences between quality of life scores between men and women. Men did have lower scores on some MOS-HIV scales (Cognitive Functioning, Pain, Quality of Life, and Health Transition) and women were lower on others (Vitality and Health Distress). In addition, there were a number
of differences in the relationships between quality of life scores, body image, and body weight. . . . The positive correlations indicated that improved quality of life was associated with improved body image” (Corless et al., 2004, pp. 294–5).

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.
2. Which of the following values from Table 1 tells us about variability of the scores in a distribution?
