Ford and Torok (2008) found that motivational signs were effective in increasing physical activity on a college campus. Signs such as 'Step up to a healthier lifestyle" and "An average person burns 10 calories a minute walking up the stairs" were posted by the elevators and stairs
in a college building. Students and faculty increased their use of the stairs during times that the signs were posted compared to times when there were no signs.

To determine whether a relationship exists between these two variables, she conducts the following pilot study. Eight- 12-year-old male volunteers are randomly selected from children attending a local junior high school. Parents of the children are asked to monitor the number of soft drinks consumed by their child over a one week period. The children are weighed at the end of the week and their weights converted into body mass index (BMI) values. The BMI is a common index used to measure obesity and takes into account both height and weight. An individual is considered obese if they have a BMI value 30. The following data or collected: child. # of soft drinks consumed BMI 1 3 20 2 1 18 3…arrow_forward

According to results obtained by Elbel, Gyamfi, and Kersh(2011), the answer is no. The researchers monitoredthe calorie content of food purchases for children andadolescents in four large fast-food chains before andafter mandatory labeling began in New York City. Although most of the adolescents reported noticing thecalorie labels, apparently the labels had no effect ontheir choices. Data similar to the results obtained showan average of M = 786 calories per meal with s =85 for n =100 children and adolescents before thelabeling, compared to an average of M = 772 calorieswith s = 91 for a similar sample of n = 100 after themandatory posting.a.

- “This paper reports the prevalence of obesity in the US based on World Health Organization’s (WHO) classification of obesity. It also reports the prevalence of individuals in the general population who use dietary modifications and/or exercise to lose weight. The main objective of this paper is to assess the relationship between obesity status, HRQL, dietary modifications, and exercise…Responses to the HRQL questions were used as dependent variables…by dichotomizing the number of reported days with poor physical health…into ≤ 14 days and > 14 days.” (Hassan et al., 2003, pp. 1227-1228) The odds ratios that result from the logistic regression defined in part (a) are: Nonoverweight: Reference Overweight: 1.08 (0.99-1.17) Obese: 1.21 (1.09-1.33) Severely Obese: 1.87 (1.64-2.12) Provide a conclusion.
