A 2007 U. S. study by Fontana, Klein, and Holloszy compared a number of factors associated with heart disease and metabolic disorders such as diabetes and blood pressure. Three groups of 21 participants in this observational study were matched for age, gender and other characteristics. The subjects in the raw vegan diet group were sedentary and had been eating a low-calorie, low-protein vegan diet composed primarily of unprocessed and uncooked plant-derived foods for at least 2 years. The subjects in the endurance runners group ran an average of 48 miles per week for an average of 21 years. The subjects in the western diet group consisted of sedentary and non-obese subjects who ate a typical western diet (characterized by high intakes of red meat, sugary treats, high-fat foods, and refined grains). All subjects in the study were healthy adults. Results of this study were published in the American Journal of Clinical Nutrition in 2006. The researchers found that the western diet group was more likely to have borderline-high to high blood pressure compared to the raw vegan diet group. Furthermore, 50% of the western diet group had higher blood pressure than 75% of the endurance runners. Students in a statistics class were asked to summarize the results of the study. Which of the student statements is an appropriate summary? Check all that apply.

Running and sleep. sufficient sleep is important for adolescents for both their neural and psychological development. despite this, daytıme sleepiness and poor physical and psychological functioning related to chronic sleep disturbances are common. there is a growing body of evidence that exercise is associated with both better sleep and improved psychological functioning sixty participants were recruited from a high school in northwesten switzerlandthey were randomly assigned to either a running group or a control group, 30 to each group the running group ran every moming for a little over 30 minutes on weekdays for a three-week period. all participants used a sleep log for subjective evaluation of sleep, and sleep was also objectively assessed at the beginning and end of the study using a sleep electroencephalographic device that measured quantities such as sleep efficiency and time spent in the four different sleep phases. running was found to have a positive impact on both objective and subjective measures of sleep functioning what are the explanatory variable(s) and the response variable(s)? (a) outline the design of the experiment (b) (c) here are some more details on the treatment and control groups. all participants arrived at school at 7 a.m., and the running group did two laps on the track and then ran cross countrv in groups of at least four people for 30 minutes the control group remained seated at the track, worked on horpework. and interacted with each other. when the runners returned, all participants prepared for school and ate a breaktast that was provided. iwhy do you think the experimenters had the control group arrive at 7 am interact withdassmates and have breaktast together? explain. do you think having the control eroup do these activities is important for the types of conclusion that can be reached? how?
