A marketing agency is interested in the buying habits of those who shop online versus those who shop in person. In your discussion post, address each of the following and explain your reasoning as to why you picked the specific scale: a. A database is created and shoppers are classified as online or in-person shoppers. Such classifications represent data of which scale? Explain your reasoning. b. Online and in-person shoppers are to be compared on their relative incomes. Income data represent data of which scale? Explain your reasoning. c. If shoppers are also ranked from the most to the least frequent shoppers, those rankings represent data of which scale? Explain your reasoning. d. Shoppers are asked to complete a customer satisfaction survey. In response to each question on the survey, the shoppers circle one of five answers: strongly agree, agree, neutral, disagree, or strongly disagree. Their responses are data of which scale? Explain your reasoning. TERM 3 BUS 308 Week 1 DQ 2 Probability DEFINITION 3 Probability. The manager of a sandwich shop gathers data on what people spend on lunch on a particular day of the week. The results are $4.20, $4.22, $2.35, $4.32, $5.25, $6.48, $6.78, $8.59, $6.95, $5.52, $6.83, $7.35, $4.36, $9.39, $6.42.

Question : Data on the city from which members of a board of directors come represent interval data. 2. Question : Inferential statistics infer the characteristics of samples. 3. Question : The mode is which of the following? 4. Question : The standard error of the mean can be calculated by dividing by the square root of the number of values in the distribution. 5.

If the number of units assembled by each shift varies greatly from day to day, what impact will that have on the likelihood of a significant difference between the two shifts? Explain and support your response. TERM 7 BUS 308 Week 2 DQ 2 ANOVA Testing DEFINITION 7 The manager of an agency providing temporary employees to city offices is analyzing the number of days temporary hires typically work in various types of industries. The data are as follows: Legal clerical: 2, 1, 4, 4, 2, 5, 6 Accounting firms: 3, 6, 4, 5, 5, 7, 8 Insurance: 5, 4, 7, 9, 9, 8, 11 Using the data above, answer the following questions: a. Are there significant differences in the length of time temporary employees work in the different industries? b. How much of the differences can be explained by the industry? c. Which groups are significantly different from others? d. Why would a manager be focused on measuring the number of days that a temporary works each week? TERM 8 BUS 308 Week 2 Journal DEFINITION 8 BUS 308 Week 2 Journal TERM 9 BUS 308 Week 2 Problem Set DEFINITION 9 Problem Set Week Two. Problem One Suppose that an automotive parts and accessories chain is experimenting with a new sales promotion. Two similar stores are selected for the experiment. For Store 1, nothing changes. This store constitutes the control group. For Store 2, the treatment group, the promotion is implemented. Sales in hundreds of dollars over a five-day period are as follows: Control: 6, 6, 7, 10, 12, 9, 6, 5, 5, 7 Treatment: 2, 5, 2, 4, 7, 1, 2, 3, 4, 5 The expectation that sales will be higher in the treatment group makes this a one- tailed test; the alternate hypothesis is m1 < m2. Use Excel to determine whether differences between the two groups are statistical TERM 10 BUS 308 Week 2 Quiz DEFINITION 10 1. Question : How is the sum of squares unlike either the standard deviation or the variance? 2.
