But Keurig's patent on K-cups, the plastic pods used to brew the coffee, is expected to expire this year, allowing other companies to better compete. Suppose a potential competitor has been conducting blind taste tests on its blend and finds that 47% of consumers strongly prefer its French Roast to that of Green Mountain Coffee Roasters, After tweaking its recipe, the competitor conducts a test with 144 tasters, of which 72 prefer its blend. The competitor daims that its new blend is preferred by more than 47% of consumers to Green Mountain Coffee roasters' French Roast. What is the value of the appropriate test statistic to test this claim 4. A.t143= 0.721 B.Z = 0.721 C.t143 = 1.96 D.Z =1.96

Akiko Hamaguchi, the manager at a small sushi restaurant in Phoenix, Arizona, is concerned that the weak economic environment has hampered foot traffic in her area, thus causing a dramatic decline in sales. Her cousin in San Francisco, Hiroshi Sato, owns a similar restaurant, but he has seemed to prosper during these rough economic times. Hiroshi agrees that higher unemployment rates have likely forced some customers to dine out less frequently, but he maintains an aggressive marketing campaign to thwart this apparent trend. For instance, he advertises in local papers with valuable two-for-one coupons and promotes early-bird specials over the airwaves. Despite the fact that advertising increases overall costs, he believes that this campaign has positively affected sales at his restaurant. In order to support his claim, Hiroshi provides his restaurant’s monthly sales (in $1,000s) and advertising costs (in $), as well as the monthly unemployment rate (in %) from San Francisco County. A…

According to a study administered by the National Bureau of Economic Research, half of Americans would struggle to come up with $2000 in the event of a financial emergency. The majority of the 1900 Americans surveyed said they would rely on more than one method to come up with emergency funds if required. In the survey, 397 people said that they "certainly" would not be able to cope with an unexpected $2000 bill if they had to come up with the money in 30 days, and 553 people said they "probably" would not be able to cope. Step 1 of 2 : What percentage of Americans "certainly" would not be able to produce $2000 in the event of an emergency according to the study? Round your answer to one decimal place, if necessary.

Dentists are increasingly concerned about the growing trend of local school districts to grant soft drink companies exclusive rights to install soda pop machines in schools in return for money-usually millions-that goes directly into school coffers. According to a recent study by the National Soft Drink Association, 62% of schools nationally already have such contracts. This comes at a time when dentists are seeing an alarming increase in horribly decayed teeth and eroded enamel in the mouths of teenagers and young adults. With ready access to soft drinks, children tend to drink them all day. That, combined with no opportunity to brush, leads to disaster, dentists say. Suppose that 20 schools around the country are randomly selected and asked if they have a soft drink contract. Find the probability that the number of 'Yes" answers is A. exactly 8 B. at most 8 C. at least 4 D. between 4 and 12, inclusive

ABC enters into a contract to help DEF, a ramen restaurantto design a market strategy to compete with DEF. The contract spans twelve month. DEF will pay P80,000 at the beginning of each month. At the end of the contract, ABC either will give DEF a refund of P25,000 or will be entitled to an additional P15,000 bonus, depending on whether sales at DEF at year- end increased to a target level. At the inception of the contract , ABC estimates a 30% chance that it will not earn the bonus and calculates the contract price based on the expected value of future payments to be received. At the start of the fifth month, circumstances change and ABC revise the probability that it will earn the bonus to 80% What is the adjustment to the service revenue ?
