Step by step
Solved in 2 steps
- 1.) With the pandemic, cleaning and sanitation products have become increasingly more popular. Pfizer is trying to expand their sales and market share among producers of hand sanitizer and would like to purchase advertising space on a major TV network during prime time. CBS and NBC seem to be the most likely options but Pfizer would like to test and see if there is really a difference in the viewership (which would influence their decision). Over the past 20 weeks, CBS has averaged 5.7 million viewers on Monday nights at the 8 PM timeslot with a standard deviation of .65 million viewers. NBC on the other hand has averaged 6.2 million viewers with a standard deviation of 1.3 million viewers. a.) With an alpha of .05, construct a hypothesis test to see if there is a difference in viewership between the two networks. b.) Construct a 95% confidence interval for the difference. c.) Which network would you go with based on your tests?A company that sells digital devices has its stores in several cities in Albania. The Marketing Manager plans to transmite an advertisement for the digital camera product on local television and watch sales of that product, to see the link that exists with the number of ads transmitted and product sales. After two days, the results were presented in the following table: City Trasmitted Sales(in 000 Euro) Durrës 4 15 Sarandë 2 8 Fier 5 21 Berat 6 24 Lezhë 3 17 S S = 1.58 S = 6.1 a) What is the dependent variable?b) Construct the scatterdiagram of this connection.c) Calculate the coefficient of variation and the coefficient of determination.d) Interpret the relationship between two variables.e) What is the equation that connects these two variables? Explain the values for a and b.f) What is the expected level of sales if 10 ads are trasmittedWhen is the consideration of ethics most important a. Data collection b. Data Analysis c. Research Planning d. All of the above
- Listed below are the costs (in dollars) of flights from Bew York (JFK) to San Franciscofor US Air, Continenta, Delta, United, American, Alaska Airlines and Northwest. Usea 0.01 significance level to test the claim that flights scheduled one day in advance costmore than flights scheduled 30 days in advance. What strategy appears to be effectivein saving money when flying?n the book Business Research Methods (5th ed.), Donald R. Cooper and C. William Emory discuss a market researcher for an automaker who is studying consumer preferences for styling features of larger sedans. Buyers, who were classified as “first-time” buyers or “repeat” buyers, were asked to express their preference for one of two types of styling—European styling or Japanese styling. Of 40 first-time buyers, 11 preferred European styling and 29 preferred Japanese styling. Of 60 repeat buyers, 41 preferred European styling and 19 preferred Japanese styling. (a) Set up a contingency table for these data. (b) Test the hypothesis that buyer status (repeat versus first-time) and styling preference are independent at the .05 level of significance. What do you conclude? (Round your answer to 3 decimal places.)You wish to assess whether Los Angeles has an equitable distribution of police services among its precincts compared to nearby cities. You theorize that if police resources are distributed equitably, average response times for emergency calls should be fairly similar from one precinct to another within the city. On the other hand, if response times are much higher in some precincts than others, police resources are probably not distributed as equitably as possible. You decide to compare the City of LA to the other cities in the rest of LA County. You are hypothesizing about differences in the mean between the City of LA and other cities. State in plain English the null and research hypotheses for this study.
- The following payoff table shows profit for a decision analysis problem with two decision alternatives and three states of nature.Rebecca Chory, Ph.D., now an associate professor of communication at West Virginia University, began studying the effect of such portrayals on patients' attitudes toward physicians. Using a survey of 300 undergraduate students, she compared perceptions of physicians in 1992—the end of the era when physicians were shown as all-knowing, wise father figures—with those in 1999, when shows such as ER and Chicago Hope (1994–2000) were continuing the transformation to showing the private side and lives of physicians, including vivid demonstrations of their weaknesses and insecurities. Dr. Chory found that, regardless of the respondents' personal experience with physicians, those who watched certain kinds of television had declining perceptions of physicians' composure and regard for others. Her results indicated that the more prime time physician shows that people watched in which physicians were the main characters, the more uncaring, cold, and unfriendly the respondents thought physicians…Rebecca Chory, Ph.D., now an associate professor of communication at West Virginia University, began studying the effect of such portrayals on patients' attitudes toward physicians.

- What is price discrimination? Under what conditions are firms able to exercise price discrimination? Are consumers better off or worse off when they face a price discriminating monopolist rather than a simple monopolist? Why?Jensen Tire & Auto is in the process of deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine.
