Compute the mean observed time for each element in minutes. b. Compute the normal time for each element AND total normal time in minutes. c. Compute the allowance fraction for the operation. Assume 480 minutes per shift. d. Compute the labor standard for the operation (Note: allowances are based on % of the time worked.
