Question

The study you are reading reports a significant correlation coefftoent of -0.5 between home size and hours spent at work. You know this means: there is a weak relationship between home size and hours spent at work there is no relationship between home size and hours spent at work as home size gets larger, hours spent at work get smaller as home size gets smaller, hours spent at work gets smalls 2) Your study examines knowledge gained from your intervention using an exam score. Your participants complete a pre and post test exam which is graded on a scale of 0-100%. Which type of analysis would be appropriate? multicollinearlty chi square t-test for independent groups t-test for dependent groups 3) Your cohort study examines the relationship between watcthing two or more hours of television a day and the risk of developing osteoporosis. You find a relative risk of 5.2 (95% CI 1.8-5.4). You know this means: individuals who watch more than two hours of television a day are 5.2 times as likely to develop osteoporosis as those who do not your results are not significant so you fa l to reject the null hypothecs individuals with osteoporosis are at five times greater risk Two hours of television causes 5.2% of osteoporosis 4) You are reading a study which reports a significant correlation (r) between smoking and coffee dnnking of 0.8. You know this means: when participants smoke more their coffee drinking is decreased by 75% when participants smoke more they drink less coffee when participants smoke more they drink more coffee when participants smoke more they only drink 75% of the coffee they were drinking 5) You are reading a study which reports that if latex free products were consistently for all patients in hospitals, 43% of allergic reactions among hospitalized patients could be elminated. You know this study is reporting this: Relative risk Attributable risk for the cases Odds ratio Attributable risk for the exposed group
