Question Answered step-by-step hypotheticalstudycarriedoutbyMalhausenUniversityexaminedtherelation… hypotheticalstudy carried out by Malhausen University examinedthe relationship between physical inactivity and heart disease.They sampled 100 individuals with heart diseaseand 100 individuals without heart disease.Among those with heart disease,they found that 40 had less than 60 minutes of moderate physical activity over the previous week, 30 had between 60 and 150 minutes, and 30 had at least 150 minutes. Among those without heart disease, they found that 15 had less than 60 minutes, 30 had between 60 and 150 minutes,and 55 had at least 150 minutes. The table below displays the (fabricated) data for this hypothetical study. Physical activity was categorized as the following:             Low: <60 min activity/week            Medium: Between 60 to <150 minutes of activity/week            High: 150 minutes or more of exercise per week Physical activityHeart diseaseNo heart diseaseTotalLow401555Medium303060High305585Total100100200 What type of study design is this? Please explain your answer, and address the following points: What were the exposure and the outcome? Were comparison groups formed based on exposure or outcome? When did the outcome occur, relative to the beginning of the study?  Write out a null and alternative hypothesis for the research questionthat this study is investigating. Fill in the following table with the counts ineach cell that would be expectedif the null hypothesis from part (b) were true (given the row totals and column totals). Physical activityHeart diseaseNo heart diseaseTotalLow  55Medium  60High  85Total100100200   Do you believethere is an association between physical activity and heart disease?Run an appropriate statistical test (with a Type I error rate of 0.05)and report the p-value and your statistical and scientific conclusions. The statistical test that you run shouldalign with the hypothesesyou stated in part (b).   Math Statistics and Probability BIOST 310 Share QuestionEmailCopy link Comments (0)
