Question 1 1 1 pts Researchers are Interested in investigating the relationship between diets high in omega3 fatty acids and cancer prevention. A prospective cohort study is designed to monitor cancer incidence in a cohort of people who eat a diet rich in omega-3 fatty acids (exposed group) and a cohort of people who eat a similar diet except tor lower omega-3 intake {unexposed group). After a 20 year follow-up, the researchers found that the relative risk (RR) of cancer was 03?, 95% Cl (0.?5, 0.97]. For this example. which of the following is the correct null hypothesis that the researchers should use? C) The rlsk of developing cancer In the population of people who consume high omega3 fatty acid diets is the same as the risk of developing cancer in population of people who do not consume diets high in omega-3 fatty acids. 0 The risk of developing cancer in the study group who consume high omega-3 fatty acid diets is n_ot the same as the risk of developing cancer in study group who do not consume diets high in omega3 fatty acids. 0 The risk of developing cancer in the population of people who consume high omega-3 fatty acid diets is n_ot the same as the risk of developing cancer in population of people who do not consume diets high In omega-3 fatty acids. 0 The risk of developing cancer in the study group who consume high omega-3 fatty acid diets is the same as the risk of developing cancer in study group who do not consume diets high in omega3 fatty acids. Using the example of the prospective study of the ass between omega-3 fatty acids and cancer, which of the following best interprets the meaning of RR = 0.87? O Based on the sample data, people who developed cancer were 0.87 times less likely to have eaten a diet high in omega-3 fatty acids compared to controls who did not develop cancer. O Based on the sample data, people who developed cancer were 0.87 times more likely to have eaten a diet high in omega-3 fatty acids compared to controls who did not develop cancer. O Based on the sample data, people who consume a diet high in omega-3 fatty acids are 0.87 times at a decreased risk of developing cancer compared to people who did not consume a diet high in omega-3 fatty acids. O Based on the sample data, people who consume a diet high in omega-3 fatty acids are 0.87 times at an increased risk of developing cancer compared to people who did not consume a diet high in omega-3 fatty acids. Using the example of the prospective study of the association between omega-3 fatty acids and cancer, what decision should be made about the results of the hypothesis test using the 95% CI? O As the 95% CI does not capture the null hypothesis, the researchers should reject the null hypothesis and accept the alternative O As the 95% CI captures the null hypothesis, the researchers should fail to reject the null hypothesis which means that the null hypothesis is accepted O As the 95% CI does not capture the null hypothesis, the researchers should reject the null hypothesis and conclude that the results support the alternative O As the 95% CI captures the null hypothesis, the researchers should fail to reject the null hypothesis and conclude there is not enough evidence to support the alternativeUsing the example of the prospective study of the association between omega-3 fatty acids and cancer, what should the researchers conclude from this study? The results of this study suggest that people who consumed a diet high in omega-3 fatty acids are at a statistically significant increased risk of developing cancer compared to people who did not consume a diet high in omega-3 fatty acids. O The results of this study suggest that omega-3 fatty acids decreased the development of cancer compared to controls who did not eat high levels of omega-3 fatty acids. O The results of this study suggest that people who consumed a diet high in omega-3 fatty acids are at a statistically significant decreased risk of developing cancer compared to people who did not consume a diet high in omega-3 fatty acids. O The results of this study are inconclusive because the sample result is captured in the 95% Cl. Therefore, we cannot tell for sure whether omega-3 fatty acids are associated with a decreased risk of developing cancer. Using the example of the prospective study of the association between omega-3 fatty acids and cancer, which of the following choice best defines the 95% CI? O The 95% CI of RR was found to be (0.75, 0.97). 95% of confidence intervals obtained in a similar manner and through repeated sampling would capture the true population RR We are 95% certain that the confidence interval (0.75, 0.97) captures the true population RR. We are 95% confident that each person in the population has a AR between 0.75 and 0.97. O We expect that the risk of developing cancer in the exposed group is between 0.75 and 0.97 with 95% confidence O The true population RR lies between 0.75 and 0.97 with 95% probability
