(4 points) 2- Of 169 women having breast cancer and a familial risk factor, 27 had an inherited BRCA1 mutations. Based on this information, estimate the prevalence of BRCA1 mutation in women with familial breast cancer. Include a 95% confidence interval for the prevalence. (6 points) A simple random sample of 262 leukemia cases consisted of 150 males and 112 females. Does this provide evidence of a gender preference for the disease? (Observed proportion, male = 150/(150 + 112) = 0.5725. Test HO: p = 0.5 and a 0.05 significance level) (4 points) 4- A- How large a sample is needed to estimate the incidence of female breast cancer in a population with 95% confidence and a margin of error that is no greater than 1% (0.01)? Assume that the expected incidence proportion in the population is 3% (0.03). (4 points) Page 1 of 2 216 words English (United States) { Accessibility: Good to go FocusES 126%AutoSave O OFF A A .
