In 2009 a survey found these airline preferences for people in Southeast Asia when choosing to fly to China: 40%, Thai Airlines; 41%, Singapore Airlines; and 19%, Cathay Pacific. In 2011 this survey was repeated, and from a sample of 1,000 responders, 365 chose Thai, 540 chose Singapore, and 95 selected Cathay Pacific. Can you conclude that the consumers still have the same purchase patterns?
A CBS News poll involved a nationwide random sample of 651 adults, asked those adults about their party affiliation (Democrat, Republican or none) and their opinion of how the US economy was changing ("getting better," "getting worse" or "about the same"). The results are shown in the table below.
If we randomly select one of the adults who participated in this study, compute: (round to four decimal places)a.P(affiliated with neither party) = b.P(better) = c.P(better|affiliated with neither party) = d.P(affiliated with neither party|better) = e.P(affiliated with neither party and better) =
In June 2015, Gallup conducted a poll of a random sample of 14802 adults to determine the well-being of people living in the United States. One question asked, "Did you exercise at least 30 minutes for 3 or more days in the past week?" In the survey, 57.3% of males and 42.7% of females responded yes to this question. Which of the following is true about this scenario?A. 57:3% and 42.7% are both statistiesB. 57.3% and 42.7% are both parameter.C. If we took another random sample of 14802 adults, we would expect to get the exact same results.

- 7. Some years ago, a new brand of toothpaste was introduced in the United States. According to its advertisements, studies showed that it had "considerable success" in improving the health of a person's teeth. Suppose that these studies were designed in the following way. The manufacturer of this toothpaste chose three samples of seven people; the first sample agreed to use the new brand, the second sample used Brand A, and the third sample used Brand B. After six months, a dentist examined each person's teeth and scored the health of his or her teeth on a scale of 0 (lowest possible score) to 100 (highest possible score). The results were as follows: New Brand Brand A Brand B 65 58 54 71 60 38 53 63 43 55 90 61 34 95 94 82 89 96 77 62 82 The manufacturer of the new toothpaste says that the average score for the new brand is 2 points higher than for Brand A and 4 points higher than for Brand B.

- Question 1 The Rotary Club is holding a pizza sale to finance outreach projects. The Club made an agreement to purchase pizza from Pizza Hut at a 30% discount which the Rotary Club can then resell for a profit. It is expected that of the 500 families in the community, at most 70% will buy pizza. Based on a survey of their personal preferences, the students believe that they should order no more than 120 cheese pizzas, no more than 150 pepperoni pizzas, and no more than 100 vegetarian pizzas. They also want to make sure that at least 20% of the total pizzas are cheese and at least 50% of the pizzas are pepperoni. The standard price (before discount) for the cheese, pepperoni and vegetarian is $12, $15 and $14, respectively. The Rotary Club makes a profit of 10%, 15% and 20%, respectively, for each cheese, pepperoni, and vegetarian pizza they resell. a) Formulate a linear programming model that would determine the optimal solution.

- answer 5.3 & 5.4arrow_forwardExercise 3.2 A three-man board, composed of A, B, and C, has held hearings on a personnel case involving an officer of the company. This officer was scheduled for promotion but, prior to final action on his promotion, he made a decision that cost the company a good deal of money. The question is whether he should be (1) promoted anyway, (2) denied the promotion, or (3) fired. The board has discussed the matter at length and is unable to reach unanimous agreement. In the course of the discussion it has become clear to all three of them that their separate opinions are as follows: • A considers the officer to have been a victim of bad luck, not bad judgment, and wants to go ahead and promote him but, failing that, would keep him rather than fire him. ⚫ B considers the mistake serious enough to bar promotion altogether; he'd prefer to keep the officer, denying promotion, but would rather fire than promote him. ⚫ C thinks the man ought to be fired but, in terms of personnel policy and…arrow_forwardFor the students of the college, the visual appearance of the campus is _______(rival/nonrival) and ______(nonexcludable/excludable).

To decide whether the initiative should be undertaken, administrators conduct a survey of the college's 1,460 students, asking each of them their willingness to pay for the beautification project. The average willingness to pay, as revealed by the survey, is $32. The benefit of the beautification initiative, as suggested by the survey, is $_______. Because the estimated benefit is _______(less/greater) than the cost, the college administrators _______(should not/should) undertake the beautification initiative.

- The goal of the consumer is to maximize the total utility or satisfaction derived from their purchase choices, given the unique budget constraint. To calculate total utility of a given combination of T- shirts and movies, one would use the following approach: Group of answer choices Use utils as a measure of utility, assigning a specific number to T-shirts and movies, and then add those together. For a given combination of T-shirts and movies, survey a group of individuals to determine an average for utils to be assigned to the number of T-shirts and movies. For a given combination of T-shirts and movies, assign a number of utils to that combination. For a given combination of T-shirts and movies, use Google to identify the number of utils associated with the number of T-shirts and movies and then sum them.arrow_forwardonly answer question 3 (number 2) .arrow_forwardThe questions has two parts: A departmental store sells stereo systems, television sets and radios.
