A researcher wants to estimate the impact prenatal care during pregnancy can have on anemia rates in pregnant mothers by conducting a retrospective case-control study on new moms. If the prevalence of anemia is approximately 39.7%, how many individuals should the researcher recruit to participate in the study if the researcher wants to be 95% confident that the margin of error is no more than 3.0%? Group of answer choices n total = 2044; n control group = 1,022; n case group = 1,022 n total = 2044; n control group = 812; n case group = 1,232 n total = 4088; n control group = 1,623; n case group = 2,465 n total = 4088; n control group = 2,044; n case group = 2,044
