Question 16 2 pts For scenario 5.3, based on the results of the previous question we conclude: The 95% confidence interval [does not capture | capture ) the value (numerical value) , we (reject | fail to reject) ' the Ho and conclude that the risk for developing cardiovascular disease (is | is not) ' ' the same between the treatment and placebo groups. Scenario 5.3: It has been suggested that excessive consumption of fatty foods leads to cardiovascular diseases. To test this hypothesis, a researcher gathers a sample of 250 participants and randomly divides them into two groups. The treatment group are required to take a supplement (which is high in cholesterol) three times a day, whereas the placebo group only takes a sugar pill three times a day. After one year of experimentation, the participants are given the E03 to detect for any trace of cardiovascular disease. The table below summarizes these ndings: Cardiovascular disease No cardiovascular disease Treatment group 62 5? Placebo group Scenario 5.4: Consider the following data on lung cancer and workers exposed to coal dust: Risk Factor Diseased Not Diseased Exposed 10 990 Non exposed 5 2995 Given that this was a retrospective study, answer the following questions. Question 17 2 pts For the scenario 5.4 above, we use (RR | OR) because it is a retrospective study. A study was examine the workers exposed to coal dust (risk factor) and if they diseased or not (lung cancer) (Looking backward in time). State the null and alternative hypotheses for scenario 5.4. Use the following formats to get full marks: OR not equals 2 or RR = 0 or OR equals to 0 or RR is equal to 0. Note that additional spaces or different format will cost you points. Remember, include just one space between the words in the above format only and no spaces at the end or the beginning of your answer. You are allowed to use only the words OR, RR, not, equal, equals, =, #, >,
