. A corporation desires to estimate the total number of man-hours lost, for a given month, because of accidents among all employees. Since laborers, technicians, and administrators have different accident rates, the researcher decides to use stratified random sampling, with each group forming a separate stratum. Data from previous years suggest the variances shown in the accompanying table for the number of man-hours lost per employee in the three groups, and current data give the stratum sizes.
