In a factory, only two machines, A and B, manufacture washers. Neither machine is perfect: machine A produces defective washers 14% of the time, while machine B produces defectives 10% of the time. Machine B is more efficient than machine A and accounts for 80% of the total output of washers. For purposes of quality control, a sample of washers is taken and examined for defectives. Compute the probability that a randomly chosen washer found to be defective was manufactured by machine A. Round your answer to two decimal places.

A company has two machines that produce widgets. An older machine produces 20% defective widgets, while the new machine produces only 4% defective widgets. However, the older machine produces 5 times as many widgets as the new machine does. What is the probability that a randomly chosen widget produced by the company is both produced by the new machine and is not defective?

Assume that a factory has two machines ??A_1 and ??A_2 . Past records shows that machine ??A_1 produces 60% of the items of output and machine ??A_2 produces 40% of the items. Further, 2% of the items produced by machine ??A_1 were defective and only 1% produced by machine ??A_2 were defective. If a detective item is drawn at random, what is the probability that it was produced by machine ??A_1 ?

Problem 1: See Dataset HIFA19Q1 .mtx In a packing plant, a machine packs cartons with jars. It is supposed that a new machine will pack faster on the average than the machine currently used. To investigate this issue, the times it takes each machine to pack forty cartons, twenty each, are recorded. Conduct different types of descriptive analysis of the data of this experiment as outlines in the questions below: 1. Use a suitable graphical method to compare the packing...

To avoid creeps from taking covert photos, iPhones bought in Japan (and seemingly also South Korea) cannot be muted when using the camera. The mandatory shutter sound was installed to reduce voyeuristic “up-skirt” photography - especially in crowded places like rush-hour trains. The chips responsible for the camera’s sound are produced at two manufacturing plants; one in Korea, and the other in Japan. The Korean factory makes 40% of the chips, while the Japanese plant produces the remaining 60%. Quality...
