For the time being, the air traffic control system in the United States is runby the federal government. Several groups disagree with this and wouldlike to privatize the air traffic control system. Among the arguments givenfor privatization is that flight delays are much too common in the UnitedStates. A first step in deciding if, indeed, delays in the U.S. are "toocommon" might be to compare the flight delay information from the U.S.and other nations.You have in front of you the following chart, which summarizes theinformation from three samples of flights from the past six weeks. One ofthe samples is composed of domestic U.S. flights, one is composed ofdomestic Canadian flights, and one is composed of domestic British flights.The information recorded for each flight is the time (in minutes) that theplane was late to the arrival gate.

As operations manager of Holz Furniture, you must make a decision about adding a line of rustic furniture. In discussing the possibilities with your sales manager, Steve Gilbert, you decide that there will definitely be a market and that your firm should enter that market. However, because rustic furniture has a different finish than your standard offering, you decide you need another process line. There is no doubt in your mind about the decision, and you are sure that you should have a second process. But you do question how large to make it. A large process line is going to cost $450,000; a small process line will cost $300,000. The question, therefore, is the demand for rustic furniture. After extensive discussion with Mr. Gilbert and Rosalita Ferrera of Ferrera Market Research, Inc., you determine that the best estimate you can make is that there is a two-out-of-three chance of high demand resulting in $600,000 profit from sales and a one-out-of-three chance of low demand…

Need help with parts (a) to (g) on this homework problem. Make sure the answers are lengthy. Also, make sure your handwriting is neat and readable. Below the homework problem is a screenshot of an excel spreadsheet with data for this problem. If there is one thing engineers like, it is a good pizza that is delivered in a timelymanner. A particular pizza chain is thinking about offering a guarantee of “lessthan 30 minutes, or it’s free” on all of its deliveries. If the pizza business can pullthis off, they will impress customers across the nation, but having to walk thispromise back would be devastating to the reputation of the business. However,the CEO will not green light this policy if it means taking a substantial hitto profits. Accounting has run some numbers, and they have determined thatthe business can only miss 5% of all deliveries before the costs of the misseddeliveries begin to impact profitability. The CEO agrees to a pilot test. 120drivers time their deliveries with a…
An Employee Value Proposition (EVP) is about defining the essence of a company. The EVP is the value an employee receives from the employer; it defines the commitment the company will make to develop the employee in exchange for the effort the employee puts in to benefit the company. But do all agree on what makes a unique and compelling EVP? A study showed that 14% of business executives, 36% of HR leaders, and 31% of employees say that compensation (pay and rewards) makes for a unique and compelling EVP. Assume that 200 individuals within each business group were surveyed. Complete parts (a) through (c). State the null and alternative hypotheses. Use a=0.05 The test statistic is x^2stat= The critical value = b. Determine the p-value and interpret its meaning.
Hawaii is considering building some bridges for drivers to be able to better access some of the islands. Below is a proposed map of the bridges the state is considering building. Notice that Kahoolawe does not have any bridges because these island because it is to small so we will ignore this island for the sake of the problem.

Construct a table for the connections made by the bridges and construct the graph of the bridges connecting to the other islands. Island Bridge Connecting to other islands 2.) Does the graph create an Euler circuit, an Euler path, or neither. Explain how you know. 3.) Give the tour guide a path to follow to visit every bridge between the island. 4.) To create an Euler circuit, what bridge(s) should you go over twice, use the fewest number of bridges as possible.
2. Many municipalities offer a variety of fare options for public transportation. This allows high use travelers a choice to pay a lower fare as a benefit of being a high user. The Transit Co. of Blue City, TX has three separate monthly bus fare options to choose from. The first is a standard “per ride" fare of $1.25 per ride. The second allows the rider to purchase a discount card. The cardholder pays $21 at the start of the month plus a fee of S0.50 per ride. Option 3 is a flat fee option where the rider pays $40 for thee month and may ride any bus at no additional cost during the month. Define the variable x to be the number of rides you take each month. Express each option as a function of x. Graph all three functions on the same set of axes. What is the break even number of rides between the options? If you only take 10 rides a month what option should you choose? If you take 40 rides a month what option should you choose? Watch the video posted in the Capstone #1 area involving…

There are several risks and costs associated with the airline's decision to overbook flights. If too many passengers show up, the airline may need to offer incentives for customers to give up their seats, which can be costly. If too few passengers show up, the airline may be forced to fly with empty seats, resulting in lost revenue. Furthermore, overbooking can lead to negative publicity and damage to the airline's reputation if too many customers are bumped from their flights. In terms of strategy, the airline must weigh the potential benefits of overbooking (maximizing revenue by filling as many seats as possible) against the potential risks and costs. The airline may also consider adjusting its overbooking policy based on factors such as the route, time of day, and historical data on no-show rates for specific flights. Overall, effective demand forecasting and capacity planning are crucial for the airline to optimize its operations and profitability while minimizing negative…
Consider a remote town in which two restaurants, All-You-Can-Eat Café and GoodGrub Diner, operate in a duopoly. Both restaurants disregard health and safety regulations, but they continue to have customers because they are the only restaurants within 80 miles of town. Both restaurants know that if they clean up, they will attract more customers, but this also means that they will have to pay workers to do the leaning. If neither restaurant cleans, each will earn $14,000; alternatively, if they both hire workers to clean, each will earn only $11,000. However, if one cleans and the other doesn't, more customers will choose the cleaner restaurant; the cleaner restaurant will make $18,000, and the other restaurant will make only $6,000. Complete the following payoff matrix using the information just given. (Note: All-You-Can-Eat Café and GoodGrub Diner are both profit-maximizing firms.) All-You-Can-Eat Café $ Cleans Up Doesn't Clean Up $ Cleans Up $ 81°F Sunny $ GoodGrub Diner $ $ If…
Suppose a certain manufacturing company produces connecting rods for 4- and 6-cylinder automobile engines using the same production line. The cost required to set up the production line to produce the 4-cylinder connecting rods is $2,500, and the cost required to set up the production line for the 6-cylinder connecting rods is $3,900. Manufacturing costs are $13 for each 4-cylinder connecting rod and $16 for each 6-cylinder connecting rod. Hawkins makes a decision at the end of each week as to which product will be manufactured the following week. If a production changeover is necessary from one week to the next, the weekend is used to reconfigure the production line. Once the line has been set up, the weekly production capacities are 6,000 6-cylinder connecting rods and 8,000 4-cylinder connecting rods. Let x4 = the number of 4-cylinder connecting rods produced next week x6 = the number of 6-cylinder connecting rods produced next week s4 = 1 if the production line is set up to…
