A)Now your team wishes to conduct a study to investigate the risk of thyroid cancer associated with living within a 500-mile radius of a nuclear power plant.Thyroid cancer is quite rare, so you decide to conduct a case-control study.Based on prior exploratory research, you hypothesize that your study will detect an odds ratio of 1.5 to reflect the risk of mortality due to thyroid cancer associated with exposure to nuclear power plants. A research assistant has reviewed the literature and estimates that approximately 30% of the population lives within a 500-mile radius of a nuclear power plant.For this analysis, you would like 80% power with a two-sided test at =0.05. You plan to enroll and equal number of cases and controls.Provide a list of the inputs used and calculate the sample size needed for this study.

Following calculation using the below listed inputs, the sample size per group is 385 and the total sample size is 770.
