There is an urban legend that mothers have increased sensitivity to and awareness of noises, in particular to that of children. A human factors psychologist finds support for the legend in the literature and now wants to confirm it. The psychologist designs a study where he recruits women that think they are going to participate in a sleep experiment where they will evaluate the comfort of different mattresses overnight. While the women slept, the psychologist introduces noises to test the minimum volume needed for the women to be awakened by the noise. The wake-up decibel data are below.

Workers at a particular mining site receive an average of 35 days paid vacation, which is lower than the national average. The manager of this plant is under pressure from a local union to increase the amount of paid time off. However, he does not want to give more days off to the workers because that would be costly. Instead he decides he should fire 10 employees in such a way as to raise the average number of days off that are reported by his employees. In order to achieve this goal, should he fire employees who have the most number of days off, least number of days off, or those who have about the average number of days off? a. He should fire employees who have the most number of days off. b. No matter who he fires, it will not increase the amount of paid time off. c. He should fire employees who have the average number of days off. d. He should fire employees who have the least number of days off.
The Boeing Company faces a critical strategic choice in its competition with Airbus Industries for the long-haul flight segment: Should it design and build a super-747 model that can carry 550 passengers at speeds around 350 mph, or a plane that can fly at 95 percent of the speed of sound but carry only about 350 passengers? As a member of Boeing's Planning Group, your task is to build a model to investigate the trade-offs involved in this decision.
Whenever Toronto has severe snow storm, many flights are delayed and Pearson International Airport has to deploy resources to clear the apron, taxiways and runaways to ensure that the airport continues to remain operational in addition to making sure all the departing aircraft are completely de-iced before they take-off. This is a critical safety measure as aircraft with ice buildup on the wings or the fuselage during take-off can be catastrophic. At the same time, the de-icing operation is extremely time consuming and costly, and must be accurately factored into the forecast of an airport's operation to ensure optimal and safe performance. You are the Operations Manager at Pearson International Airport, and after reviewing the snowfall patterns for the last 10 years, you have determined the following probabilities: The chance of having a severe snow storm during the winter season is 0.15 The chance of having major flight delays during the winter season is 0.35 Amongst the days there…
California Wine producer Chill Wines has in their line a mid-market chardonnay, of whichthey produce 200,000 bottles a year. They have been bottling their wines with natural corkclosures, which are known to have sealing issues resulting in the spoilage of wine, aproblem that is worse in their chardonnay than in the other wines they sell. This problem,which results in a 15% spoilage rate for their chardonnay, is both expensive and impactsthe company’s reputation. They have researched several other closure products on themarket and have decided to try using a new closure in a test run of 91 bottles theirchardonnay. After allowing the wine to stay in the bottles for the time it generally takes toget it from the winery to customers, they tested the run and found 16 spoiled bottles. As thecompany has a both an immediate financial and reputation risk, they want to be 90% surethat changing the closures will help limit wine spoilage. What do their results suggest? a)What is known? What…
In May 2008, CNN reported that Sports Utility Vehicles (SUVs) are plunging toward the "endangered list". Due to soaring oil prices and environmental concerns, consumers are replacing gas-guzzling vehicles with fuel-efficientsmaller cars. As a result, there has been a big drop in the demand for new as well as used SUVs. A sales manager of a used car dealership for SUVs believes that it takes more than 90 days, on average, to sell an sUV. In order to test his claim, he samples 40 recently sold SUVs and find that it took an average of 95 days to sell an SUV. He believes that the population standard deviation is fairly stable at 20 days. Determine if the sales manager's claim is justifiable at 0.05
The management at Massachusetts Savings Bank is always concerned about the quality ofservice provided to its customers. With the old computer system, a teller at this bank could serve,on average, 22 customers per hour. The management noticed that with this service rate, thewaiting time for customers was too long. Recently the management of the bank installed a newcomputer system, expecting that it would increase the service rate and consequently make thecustomers happier by reducing the waiting time. To check if the new computer system is moreefficient than the old system, the management of the bank took a random sample of 70 hours andfound that during these hours the mean number of customers served by tellers was 27 per hourwith a standard deviation of 2.5. Testing at the 1% significance level, would you conclude thatthe new computer system is more efficient than the old computer system?
In 1969, the National Academy of Sciences published a study titled "Resources and Man." That study places "the earth's ultimate carrying capacity at about 30 billion people, at a level of chronic near-starvation for the great majority (and with massive immigration to the now less-densely populated lands)!" The study goes on to state that 10 billion people is "close to (if not above) the maximum that an intensively managed world might hope to support with some degree of comfort and individual choice." The world population in 1990 was 5.283 billion; in 2000, it was 6.082 billion. (a) Develop the mathematical model that represents world population. (Write your model in terms of t, where t is the number of years after 1990. Let p represent the world population in billions. Round the coefficient of t to seven decimal places.) p(t) = ? (b) Use the model to predict when world population would reach the "somewhat comfortable" level of 10 billion. (Round your answer to the nearest whole…
Knowing that people have a tendency to engage in social loafing when they think there are other people around to take some of the burden, researchers think that knowing they are “alone” versus “together” will impact the way a participant performs during a tug-of-war task. In the “alone” condition, participants are blindfolded and asked to pull as hard as they can on a rope against another participant on the other end. In the “together” condition, participants are once again blindfolded and told to pull as hard as they can. However, they are led to believe that there are three people on each end of the rope (they have two team additional team members to help them). The researchers find that those in the “alone” condition pull much harder (as measured by a weight sensor that measures pounds per square inch on a scale from 0 to 500 pounds) than those in the “together” condition. Which of the following is the independent variable? Pulling strength Weight sensor Social loafing…
