Chapter 12.2, Problem 35E
Let’s talk about a modified Borda count method. Suppose that there are three candidates, and on each ballot the top-ranked candidate gets eight points, the second candidate gets four points, and the last candidate gets one point.
(a) Do you think this modification would change the results of some elections? Explain your answer. (You might consider reworking some of the exercises or example problems with this modification to help you decide.)
(b) If you answered yes to part (a), describe the circumstances under which certain election results would change.

Tasks:
A company manufactures two electronic products: Chipsets and LCD. Each product contributes
differently to the profit. The production process is subject to constraints related to labour,
manufacturing space, raw materials, and production time. You are required to determine the optimal
production quantities for each product to maximize profit:
• Develop and formulate a Linear programming model for the variables and constraints from the
above context as given in Table 1 & 2. Assume Right-Hand Side (R.H.S) values for all elements
and find the maximum profit and optimal variable values using graphical method
(40%).

very time you conduct a hypothesis test, there are four possible outcomes of your decision to reject or not reject the null hypothesis: (1) You don’t reject the null hypothesis when it is true, (2) you reject the null hypothesis when it is true, (3) you don’t reject the null hypothesis when it is false, and (4) you reject the null hypothesis when it is false.
Consider the following analogy: You are an airport security screener. For every passenger who passes through your security checkpoint, you must decide whether to select the passenger for further screening based on your assessment of whether he or she is carrying a weapon. Suppose your null hypothesis is that the passenger has a weapon. As in hypothesis testing, there are four possible outcomes of your decision: (1) You select the passenger for further inspection when the passenger has a weapon, (2) you allow the passenger to board her flight when the passenger has a weapon, (3) you select the passenger for further inspection when…

Rather than checking every HDMI cable, the manager plans to take a simple random sample of size 62 in order to estimate the proportion of defective HDMI cables in the shipment. If the sample proportion of defective HDMI cables, p̂p̂, is greater than 0.0323 (there are more than two defective HDMI cables in the sample), the manager will file a complaint and request a new shipment.

The first number in the warranty code is the free-replacement period; the second number is the prorated-credit period. Under this warranty, if a battery fails within 39 months of purchase, the manufacturer replaces the battery at no charge to the consumer. If the battery fails after 39 months but within 50 months, the manufacturer provides a prorated credit toward the purchase of a new battery. The manufacturer assumes that X, the lifetime of its auto batteries, is normally distributed with a mean of 44 months and a standard deviation of 3.6 months.
