Homework Answers
a) P(first and second component both fail) = 0.01 x 0.01 = 0.0001
b) P(one or both of the first and second components failed) = 1 - P(both components didnt fail)
= 1 - 0.99x0.99
= 0.9801
c) P(second component fail | first component fail) = 0.01
(because the events are independent)

Manufacture of a certain component requires three different machining operations. The amount of time each operation requires (operation time) is normally distributed with mean 10 and variance 4. The three operation times are independent. Referring to the previous manufacturing example, now suppose that the cost for the first machining operation is $1 per minute. That for the second and third operations are $2 per minute and $3 per minute, respectively. What is the probability that total cost for making the...

Q3. Commodore 64's computer has three critical parts, each of which is needed for the computer to work. The computer runs continuously as long as the three required parts are working. The three parts have mutually independent exponential lifetimes before they fail. The expected lifetime of parts 1, 2 and 3 are 10 weeks, 20 weeks and 30 weeks, respectively. When a part fails, the computer is shut down and an order is made for a new part of that...

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...

2. A device consists of two redundant subunits; only one needs to be working for the device to function. The first subunit has two parts Wi and W2, and the second has two parts W3 and W4. In each subunit, both parts must function for the subunit to work. The four parts are independent identical and equally reliable, with probability p- 0.9 of functioning. (a) What...

Western Components, Inc. manufactures a variety of pinions,
gears and other component parts used by companies around the world.
Their major customer is a large west-coast aircraft manufacturer.
Currently, Western has substantial unused capacity due to a
downturn in production for this major customer. This in turn has
caused a significant drop in profits at Western since their workers
are highly skilled and Western does not want to reduce head-count
during this downturn which they expect to be temporary. Sally...
