The company has two machines that produce certain items. Machine 1 produces 40 % of the the items, and machine 2 produces 60% of the items. Machine 1 produces 3% of defective items and machine 2 produces 5% of defective items. a. The probability that a randomly selected produced item is defective is b. If a randomly selected item is found to be defective, probability that it is produced on machine 2 is

(b) At a factory where bolts are produced, machines A, B, C produce respectively 25%, 35% and 40% of all bolts. Of the output of these machines, defects constitute 5%, 4% and 2% respectively. A bolt selected at random from the production turned out to be defective. What machine was the most likely to have produced this defective bolt? (give the probability it was this machine.) [5]

A company uses 2 machines to produce rods. The length of the rods from both machines follow exponential distributions. Machine A produces rods with a mean length of 6 inches, while machine b produces rod with mean length of 10 inches. In the factory 1/3 of rods are produce by machine A and 2/3 by machine B. 2 rods are selected from a defective batch, both have a length greater than 12. What is the probability the defective rods were...

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?

Machines A and B make components, which are then placed on a conveyor belt. Of those made by machine A, 93% are acceptable. Of those made by machine B, 95% are acceptable. Machine A makes 60% of the components and machine B makes the rest. Find the probability that a component selected at random from the conveyor belt is a) made by machine A b) made by machine A and acceptable c) made by machine B and acceptable d) made...

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...

Higbee Manufacturing Corp. has recently received 5 cases of a certain part from one of its suppliers. The defect rate for the parts is normally 5%, but the supplier has just notified Higbee that one of the cases shipped to them has been made on a misaligned machine that has a defect rate of 97%. So the plant manager selects a case at random and tests a part. a. What is the probability that the part is defective? b. Suppose...
