As an analyst, we would like to perform a work sampling study on an assembly line. The jobs can bedifferentiated on the basis of the product size: A, B, and C. We perform a study over a five-week periodthat equals to 200 working hours. There are 12 workers to be examined. In total, we perform 1140observations. Yet, the worker absences lead to 15 worker-day deduction from the total working hourswhere workers work 8 hour each day. The study results are tabulated below. Q: For the C size product, construct a 96% confidence interval about the mean assembly time per productin terms of hours.a) (0,3702 0,4298)b) (0,4004 0,3996)c) (0,1805 0,1209)d) (0,3746 0,4254)e) (0,1253 0,1761)
