b. The true population proportion of customers who live in an urban area exceeds 40% c. The average (mean) number of years lived in the current home is less than 13 years d. The average (mean) credit balance for suburban customers is more than $4300 I have been assigned to analyze the speculated data listed above by performing hypothesis test for each of the above situations (using the Seven elements of a Test Hypothesis with a=.05) in order to see if there is evidence to support my manager’s beliefs in each case (a-d), explain my conclusion in simple terms, compute the p-value with the interpretation, follow up with computing 95% confidence intervals for each of the variables described in a. b. c. d. along with interpreting these intervals. This paper will also include an Appendix with all the steps in hypothesis testing, as well as the confidence intervals and Minitab output In order to understand how hypothesis testing is done it is important that you know the elements of the Test of Hypothesis, and what each step means. The Seven elements of a Test of Hypothesis are: 1. Null
The department store of AJ Davis is attempting to find out more information about their credit customers. They have taken a sampling of 50 credit customers using several different variables. The data collected for several of those variables and the relationship between variables have been interpreted with detailed statistical analysis to summarize the pertinent customer information. The first variable interpreted is location, which is categorical. AJ Davis listed customer location in three subcategories: urban, suburban, and rural.
Under what conditions might people answer questions differently if they are promised confidentiality? RES 320 Week 2 Individual Assignments from Readings Resources: Business Research Methods Write a 150-word response to each of the following questions: • Chapter 5: Discussion Questions 2 and 3 • Chapter 7: Discussion Questions 1, 2, and 5 Discussion Questions When does anonymity make a difference in the accuracy of responses? When would the use of focus groups be a better technique than questionnaires? How do you determine the reliability of secondary sources?

Descriptive- Describing the people that use their products. • A firm is considering hiring American celebrity Paris Hilton to endorse its products. Casual- The relationship between the product and celebrity endorsement (is the product bought solely on the endorsement of the celebrity). • British Airways would like to test in-flight Internet services on one of its regular flights from New York to Tokyo.
If you choose 40 random employees from the corporation, the standard error would equal 6/Square root of 40 = .95 days. The 12 days in this department corresponds to (12-8.2)/.95 = 4 standard errors above the corporation average of 8.2. This is much higher than two or three standard errors, and it appears to be beyond chance variation. Chapter 9 Exercise 3 The p- value tells you how likely it would be to get results at least as extreme as this if there was no difference in the taste and only chance variation was operating. In this problem, p-value of 0.02 means that, if there is no difference in taste, then there is only 2% chance that 70% or more people would declare one drink better than the
Probabilities of these events are estimated to be 0.6 and 0.4 respectively. With a high response, gross revenues of $2,000,000 are expected; with a low response, the figure is $450,000. If it starts with a North American test market, it might find a low response or a high response with probabilities 0.3 and 0.7, respectively. ThisPLE has developed a prototype for a new snow blower for the consumer market. This can exploit company's expertise in small-gasoline-engine technology and also balance seasonal demand cycles in the North American and European markets to provide additional revenues during winter months.

Verizon told the FCC in December of 2009 that it does not charge for accidental Internet connection. However three senators from the Senate communications, technology, and Internet subcommittee sent a letter to FCC Chairman Genachowski to monitor Verizon’s billing practices. Verizon agreed to pay $25 million to settle these “mystery” data charges levied on affected consumers. In addition to reimbursing current and former customers, Verizon will offer data blocks to customers who do not want access to undesirable content, clearly explain its data plans, improve customer service training, and frequently report to the FCC on its business
