Required informationA sociologist is interested in surveying workers in computer-related jobs to estimate theproportion of such workers who have changed jobs within the past year.In a sample of 90.0 workers, 20 of them had changed jobs within the past year. Estimate the sample sizeneeded so that the 95% confidence interval will specify the proportion to within 10.02. (Round the finalanswer to the nearest whole number.)
