Dell has decided to improve its products' cooling system to achieve better performance and enhance theirefficiency. To do so Dell determined its need to design 25,000 new hybrid cooling fans. The company has twochoices, either to Make, or Outsource the hybrid cooling fans. In the Making process, Dell must pay $5 per fanwith a production line cost of $5,000. The process could be either a success or a failure, with a probability of0.65 in case of success and 0.35 in case of failure. If the making process was successfiul, no additional fees willbe incurred. On the other hand, if the process was a faiiure, then 15% of total fans made must be fixed with afixing cost/defective fan of $3.In the outsourcing process, the cost per fan depends on the market conditions. According to previous studies,the market could have two approaches, the first approach will cost Dell $8 per fan, while the second marketapproach will cost Dell $4.5 per fan and a Tax of 13% &:20% defective fans with a probability of 0.7.• 45% defective fans with a probability of 0.3.a fixing cost/defective fan of $2.5.The first market approach has 0.8 probability, and the second approach has 0.2 probability.EMV "Outsourcing - Approach 2" is$124,312.5$134,312.5$14,312.5

We are required to determine the EMV of the Outsourcing approach 2.

A salon owner estimates the number of clients she is expecting during the festive season to be 20% during Monday to Wednesday, 20% on Thursday and 60% over the weekend. She therefore hires additional staff to assist during the weekend to meet the client demand. She however only observes 30% during Monday to Wednesday, 20% on Thursday and 50% over the weekend in the first week of December. The salon owner is uncertain whether she should reduce the planned staff for the December festive period due the observed trend or not. She conducts a statistical test at α = 0.05 to determine if the observed trend fits the expected trend. Which of the following statements is true? A. The conclusion of the test is that she should not keep the additional staff for the weekend. B. The df for this test is 3. C. The p-value is greater than α. D. The null hypothesis is that the observed trend is different to the expected trend. E. The test statistic is χ2 = 5.33.
You are concerned that nausea may be a side effect of Tamiflu, but you cannot just give Tamiflu to patients with the flu and say that nausea is a side effect if people become nauseous. However, past research indicates that about 30% of people who get the flu experience nausea, and you believe that the percentage of those who experience nausea while having the flu and taking Tamiflu will be greater than 30%, which would indigate that nausea is a side effect of Tamiflu. If you are going to test this claim at the 0.05 significance level, what would be your null and alternative hypotheses? Họ: H1: What type of hypothesis test should you conduct (left-, right-, or two-tailed)?
Zordon is a new competitor in the production of power rangers, and has to train its employees in theprocess of making power morphers. To increase the speed of learning, Zordon will give a bonus to theemployee with the lowest cumulative average time per unit after eight units are completed. Jason took 50hours to complete the first unit, and is subject to an 80% learning curve. Rocky took 60 hours to completethe first unit, and is subject to a 70% learning curve. Tommy took 40 hours to complete the first unit, andis subject to a 90% learning curve. Andross took 55 hours to complete the first unit, and is subject to a75% learning curve. Which employee will receive the bonus?
It is known that in any given year, • 90% of the people in a city move to the suburbs; • 80% of the people in the suburbs do not move to the city. Given an initial city population of 55,000 and an initial suburb population of 77,000, what are the long-term population levels of the city and the suburb?
The Harriet Hotel in downtown Boston has 100 rooms that rent for $150 per night. It costs the hotel $30 per room in variable costs (cleaning, bathroom items, etc.) each night a room is occupied. For each reservation accepted, there is a 5% chance that the guest will not arrive. If the hotel overbooks, it costs $200 to compensate guests whose reservations cannot be honored. How many reservations should the hotel accept if it wants to maximize the average daily profit?
Sarah believes that completely cutting caffeine out of a person's diet will allow him or her more restful sleep at night. In fact, she believes that, on average, adults will have more than two additional nights of restful sleep in a four-week period after removing caffeine from their diets. She randomly selects 8 adults to help her test this theory. Each person is asked to consume two caffeinated beverages per day for 28 days, and then cut back to no caffeinated beverages for the following 28 days. During each period, the participants record the numbers of nights of restful sleep that they had. The following table gives the results of the study. Test Sarah's claim at the 0.05 level of significance assuming that the population distribution of the paired differences is approximately normal. Let the period before removing caffeine be Population 1 and let the period after removing caffeine be Population 2. Numbers of Nights of Restful Sleep in a Four-Week Period With Caffeine 24 22 24 20…
Many golfers wear wrist bracelets containing magnets because they claim the magnets improve balance and the length of shots played off the tee. A golfer would like to determine if the claim has merit and finds 200 volunteers who play golf to participate in an experiment. Half of the golfers are randomly assigned to wear a bracelet with magnets, while the other half wear a bracelet without magnets. Each golfer plays normally for a month, after which the length of their shots in a subsequent round is recorded. What is the response variable in this experiment? the age of each golfer the 200 volunteers the length of shots played by the golfers whether the golfers wear or do not wear the bracelet
The military requires to send five autonomous tanks to a remote location for a mission. While working on the requirements of the mission it has been found that for successful completion of the mission, it is necessary that at least three tanks must survive. The reliability of an individualtank is 75% for the mission and it is same for all the tanks. Determine the overall reliability of the system for successful completion of the mission
On the Great Stark island, the likelihood of a residential fire is evenly distributed at 12 per month. Residents are evenly distributed along the 64-mile perimeter of the island. The government is providing fire protection, and a fire department's fixed cost is $60,000 per month. If the travel cost to fight a fire is $2,500 per mile, what is the optimal number of fire departments?
