A researcher wants to estimate the prevalence of breast cancer among women who are between 35 and 45 years of age living in Western Visayas. How many women must be involved in the study to ensure that the estimate is precise? If national data suggest that 1 in 235 women are diagnosed with breast cancer by age 40, this translates to a proportion of 0.0043 (0.43%) or prevalence of 43 per 10,000 women. Suppose the researcher wants the estimate to be within 10 per 10,000 women with 95% confidence. What would be the sample size?
