click on “student edition”, go to cases and click on “Campbell-Ewald Pumps Awareness into the American Heart Association case”. Then, once you have read the case answer questions 2 and 3 from the case. Answer the questions in APA style.
Assume the following:
2.1. A lakefront resort is planning for its summer busy season. It wishes to estimate with 95% confidence the average number of nights each guest will stay for a consecutive visit. Using a sample of guests who stayed last year, the average number of nights per guest is calculated at 5 nights. The standard deviation of the sample is 1.5 nights. The size of the sample used is 120 guests and the resort desires a precision of plus or minus .5 nights. What is the standard error of the mean in the lakefront resort example? Within what range below can the resort expect with 95% confidence for the true population means to fall? Show the calculation; otherwise, the answer will not be accepted.

2.2. A local restaurant is planning a study on demand for meals over holiday weekends. In calculating the desired sample size for the study, the restaurant’s researcher decides to use a rule-of-thumb calculation for estimating the population dispersion. If the range of meals in the study is 0 to 30, what standard deviation does the rule-of-thumb method produce? Show the calculation; otherwise, the answer will not be accepted.

2.3. A microbrewery plans to conduct a study on beer consumption among men between the ages of 29 and 45. A pilot test indicated that men in this age category consume an average of 6 beers per week with a standard deviation of 2.3. If the microbrewery seeks a 95% confidence level and a precision of .5 beers, what size sample should be used in the study? Show the calculation; otherwise, the answer will not be accepted.

Sample Solution

stablishing a monopoly over one aspect of the production process of oil refining was labeled as horizontal integration. To eliminate his competitors, Rockefeller used his firm’s superior size to negotiate rates from the railroads that transported both his and his competitors’ oil, making it nearly impossible for his competitors to stay in business.(Doc C) This economic success occurred with a handful of businesses during the time, and shows how the tactics of horizontal and vertical integration benefited the wealthy class by giving them opportunities to become top dogs in their fields of work.
Although it may seem like there are no possible benefits with vertical integration to anyone other than the entrepreneurs, a lot of the working class was impacted by this tactic as well. The rapid growth of the manufacturing industry created a great need for unskilled workers. This demand caused mass migration, farm workers moved from rural areas of the United States to find jobs in America’s rapidly growing cities. The increase in jobs was also a draw for people in foreign countries. (Doc E) Many people immigrated to the United States in search of work and the opportunity to live the American dream. They could use these new job opportunities as stepping stones into a new life of owning land or carrying out their life aspirations that their old country couldn’t fulfill. (Doc F) This was impactful because it created a large amount of jobs that required manual work, no one needed to be skilled or knowledgeable to get a job. Also due to vertical integration, our nation became industrialized and urban just like it continues to be today. It is clear to see how prospering entrepreneurs benefited in the gilded age, but the lower working class was impacted as well given unskilled labor and a chance to start a new life, aspiring for the “American Dream”.
Big business owners benefited tremendously from the economic changes in the United States and the use of vertical integration. Some people believe that these entrepreneurs were robber barons because they got rich through ruthless means. However, many called them captains of industry because they were greatly responsible for increasing productivity, expanding markets, providing jobs, and increasing the nation’s wealth. All in all both ends of the economic scale were impacted and benefited from vertical integrat
