Refer to the previous exercise about the study of the relationship between level of physical activity and
Question:
a. Explain why it would be okay to use the theory-based method to find a p-value for this study.
b. Use an appropriate applet (for example, the Multiple Proportions applet) to find and report the following from the data: (i) the name of the statistic and its numeric value and (ii) the theory based p-value.
c. Interpret the p-value in the context of the study.
d. State a complete conclusion about this study, including significance, causation, and generalization. Be sure to explain how you are arriving at your conclusion.
e. If relevant, use an applet to find and report a set of confidence intervals appropriate for the context. Also, interpret the confidence intervals in the context of the study. If not relevant, explain why it is not particularly useful to look at confidence intervals for the parameter(s) of interest in the context of this study.
Data from previous exercise
An eight-year cohort study of 3,454 initially disease-free men and women (ages around 60 years or more) recorded the extent of physical activity the participants engaged in and whether or not they were showing signs of healthy aging (British Journal of Sports Medicine, 2013). Here is the table of summarized counts at the conclusion of the study:
