At the car production plant, the revision of 3850 units is carried out. The manager decides to conduct a lot inspection by means of a sample. He wants his study to be 98% confident and decides to allow a 5% error. Calculate the sample size to inspect a lot when: a. It starts and has never reviewed a batch so it does not have previous information b. Several reviews of batches of the same size have been carried out and a positive variability of 0.75 has been obtained
