Jet Blue is considering adding a route to the city of Minneapolis, MN. After considerable research, the company estimates that if it adds this route, there is a 60% chance of making a $900,000 profit, a 10% chance of breaking even, and a 30% chance of losing $1,400,000, Calculate the expected value of adding this new route.

An online retailer specializing in custom dog toys is considering launching brick-and-mortar stores in Upstate South Carolina. They have an opportunity to open a spot on Woodruff Road in Greenville, South Carolina next month at an upfront cost of $50,000. They believe this location has a 60% chance of success and a 40% chance of failure. If the location is successful, then it will bring the company a total of $350,000 in net profits over its lifetime. If the location is unsuccessful, then it will lose the company an additional $100,000. Complicating the Woodruff Road location decision is the fact that the company has identified an additional location in downtown Clemson. They do not need to decide on opening this additional location now; they need to decide in about 11 months whether to open it 12 months from now. The Clemson location has an upfront cost of $30,000. Without any additional information, the company believes it has a 70% of success and a 30% chance of failure. If…

The SAT and ACT exams are often used to predict a student's first-term college grade point average (GPA). Different formulas are used for different colleges and majors. Suppose that a student is applying to a university with an intended major in civil engineering. Also suppose that for this college and this major, the following model is used to predict first term GPA. GPA  =  a + b(ACT) a  =  0.6 b  =  0.2 (a) In this context, what would be the appropriate interpretation of the value of a?   The value of a is the predicted ACT score of a student who has a 0 GPA.   There is not enough information to know how to interpret the value of a.   The value of a represents the change in predicted GPA associated with an increase of 1 in ACT score.   The value of a represents the change in predicted GPA associated with an decrease of 1 in ACT score.   The value of a is the predicted GPA of a student who scored a 0 on the ACT.   (b) In this context, what would be the…

Netflix made headlines in September 2011 when it split its streaming video service and its DVD by-mail service into two companies. This decision was based on projections that streaming videos will replace DVDs in the future. In this problem, you will explore these projections. Numbers below are close to the correct values, but vary to allow more practice with this idea.  Total DVD and Blu-ray disc sales in 2009 were $8.72 billion. For the purposes of this problem, you will combine DVD and Blue-ray disk sales into one category of DVD sales. A study by In-Stat predicted that "physical disc sales will decline by $4.7 billion by 2014," and that "streaming, on the other hand, should grow from its current $2.1 billion to $6.3 billion over the same time period (2009–2014)."12 What is the slope, including units, of the model for DVD sales?

Large companies typically collect volumes of data before designing a product, not only to gain information as to whether the product should be released, but also to pinpoint which markets would be the best targets for the product. Several months ago, I was interviewed by such a company while shopping at a mall. I was asked about my exercise habits and whether or not I'd be interested in buying a video/DVD designed to teach stretching exercises. I fall into the male, 18-35-years-old category, and I guessed that, like me, many males in that category would not be interested in a stretching video. My friend Holly falls in the female, older-than-35 category, and I was thinking that she might like the stretching video. After being interviewed, I looked at the interviewer's results. Of the  89  people in my market category who had been interviewed,  20  said they would buy the product, and of the  103  people in Holly's market category,  28  said they would buy it. Assuming that these…

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

If P(A) = 0.52, P(B) = 0.45 and P(A u B) = 0.76, then P(B | A) = (Enter a number between 0 and 1, using two decimal points)

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 52 stocks traded on the NYSE that day showed that 18 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.10What is the test statistic for this sample? Use ˆpp^ rounded to 4 decimal places. (Report answer accurate to 4 decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to 4 decimal places.)p-value = The p-value is... less than (or equal to) α greater than α This p-value leads to a decision to... reject the null…
