The manager of a men’s clothing catalog measured the market’s response to a $6 decrease in the usual price of his company’s oxford shirts by conducting a sales experiment. An A-B split was used to divide the company’s 120,000-customer mailing list into two groups. Customers in the control group were sent catalogs listing oxford shirts at their usual price of $40. Customers in the test group were sent catalogs listing the price of oxford shirts at $32.80. During the period of the test, customers in the control group purchased 700 oxford shirts, and customers in the test group purchased 889 oxford shirts.
What is the independent variable in this sales experiment? What is the dependent variable in this sales experiment?

What is price elasticity indicated by the results of this experiment.
A salesman for a new manufacturer of cellular phones claims not only that they cost the retailer less but also that the percentage of defective cellular phones found among his products, ( p1 ), will be no higher than the percentage of defectives found in a competitor's line, ( p2 ). To test this statement, the retailer took a random sample of 130 of the salesman's cellular phones and 110 of the competitor's cellular phones. The retailer found that 10 of the salesman's cellular phones and 5 of the competitor's cellular phones were defective. Does the retailer have enough evidence to reject the salesman's claim? Use a significance level of α=0.05 for the test. Step 5 of 6 : Determine the decision rule for rejecting the null hypothesis H0 . Round the numerical portion of your answer to three decimal places.

- A salesman for a new manufacturer of cellular phones claims not only that they cost the retailer less but also that the percentage of defective cellular phones found among his products, ( p1 ), will be no higher than the percentage of defectives found in a competitor's line, ( p2 ). To test this statement, the retailer took a random sample of 185 of the salesman's cellular phones and 150 of the competitor's cellular phones. The retailer found that 22 of the salesman's cellular phones and 11 of the competitor's cellular phones were defective. Does the retailer have enough evidence to reject the salesman's claim? Use a significance level of α=0.05 for the test. Step 1 of 6 : State the null and alternative hypotheses for the test.arrow_forwardWhat sampling technique is used? In a research class of 40 students, the teacher divides the class into five groups, each with eight members per group. The teacher then asked the class to choose their group members based on interests, compatibility, and rapport. After the selection was made, the teacher realized that the abilities per group were uneven. He then reshuffled some members of the group to achieve equilibrium among the groups. The teacher needs ten students to represent each group. He selected one male and one female from each group based on academic performance, leadership skills, and social skills as qualities that will embody as representatives per group.arrow_forwardTourism patterns are difficult to forecast; they normally vary from country to country and sometimes even between places quite close to each other. In Hong Kong, a survey asked 1,600 people their favorite Asian destination for a short holiday. The results were as follows: 43% go to China, 23% go to Thailand, 20% go to the Philippines, 5% go to Cambodia, and the rest choose other countries. The same survey has been carried out in Macau, China only 1 hour from Hong Kong by jet boat, and the results were as follows: 48%, China; 20%, Thailand; 22%, the Philippines; 3%, Cambodia; and the remaining, other destinations. Would you conclude that the patterns are the same in the two cities?arrow_forward
- 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. Would you agree with the manufacturer's advertisements? Explain.arrow_forwardFor the students of the college, the visual appearance of the campus is _______(rival/nonrival) and ______(nonexcludable/excludable). Thus, the visual appearance would be classified as a public good. Suppose the college administrators estimate that the beautification initiative will cost $34,980. 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 calculation of the benefit of the beautification initiative relied on the ability of the administrators to capture the true willingness to pay of each student accurately.

It would like to investigate this relationship in order to predict the number of orders to be filled based on the weight of the mail. From an operational perspective, knowledge of the number of orders to be filled will help in the planning of the order-fulfillment process. A sample of 15 mail shipments is selected within a range of 200 to 700 pounds. The results are as follows.

- Recently the European Community (EC) decided to lower its subsidies to makers of pasta. In deciding by what amount to reduce total subsidies, experiments were carried out for determining the possible reduction in exports, mainly to the United States, that would result from the subsidy reduction. Over a small range of values, economists wanted to test whether there is a positive correlation between level of subsidy and level of exports. A computer simulation of the economic variables involved in the pasta exports market was carried out. The results follow. Assuming that the simulation is an accurate description of reality and that the values obtained may be viewed as a random sample of the populations of possible outcomes, state whether you believe that a positive rank correlation exists between subsidy level and exports level over the short range of values studied Qarrow_forwardA quality engineer in charge of a coffee filter pack production line was concerned about the weight (in grams) of the filter packs being produced.

It deals with what is right and what wrong while doing business”. But to the contrary, evidences show that some business organizations are involved in different unethical practices to increase their profit at the risk of many people’s money, health and lives. As a business ethics student you are required to address the following questions: Describe five unethical practices adopted by business organizations in Oman. You may find it form newspapers, magazines etc. or from your own experiences and observation if any. And Analyze each of these unethical practices and explain how these unethical practices affect the people and society as a whole. And Suggest the ways to overcome each of these unethical practices.arrow_forward
