Chapter 16.2, Problem 8E

The effect of a restricted diet in the treatment of autistic children was examined in the paper “Gluten, Milk Proteins, and Autism: Dietary Intervention Effects on Behavior and Peptide Secretion” (Journal of Applied Nutrition [1991]: 1–8). Ten children with autistic syndrome participated in the study. Peptide secretion was measured before diet restrictions and again after a period of restricted diet. The resulting data follow.

Do these data suggest that the restricted diet was successful in reducing mean peptide secretion? Test the relevant hypotheses using the signed-rank test.

Stressed-Out Bus Drivers. Previous studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. In the paper, “Hassles on the Job: A Study of a Job Intervention With Urban Bus Drivers” (Journal of Organizational Behavior, Vol. 20, pp. 199–208), G. Evans et al. examined the effects of an intervention program to improve the conditions of urban bus drivers.Amongother variables, the researchers monitored diastolic blood pressure of bus drivers in downtown Stockholm, Sweden. The data, in millimeters of mercury (mm Hg), on the WeissStats site are based on the blood pressures obtained prior to intervention for the 41 bus drivers in the study. Use the technology of your choice to do the following. a. Obtain a normal probability plot, boxplot, histogram, and stemand-leaf diagram of the data. b. Based on your results from part (a), can you reasonably apply the one-mean t-test to the…

Recent research has demonstrated that music-based physical training for elderly people can improve balance, walking efficiency, and reduce the risk of falls (Trombetti et al., 2011). As part of the training participants walked in time to music and responded to changes in the music's rhythm during a 1-hour per week exercise program. After 6 months, participants in the training group increased their walking speed and their stride length compared to individuals in the control group. The following data are similar to the results obtained in the study.   Exercise Group Stride Length Control Group Stride Length 24 26 25 23 22 20 24 23 26 20 17 16 21 21 22 17 22 18 19 23 24 16 23 20 23 25 28 19 25 17 23 16 Do the results indicate a significant difference in the stride length for the two groups? Use a two-tailed test with ?=.05 (By hand and with SPSS)
