Exercise 2. Use the final project data to complete the following questions. Collaborate with your project partners and produce the Excel outputs for the first analysis listed on the project guidelines below. Read and follow the instructions carefully. The Excel outputs such as tables, graphs, summary statistics produced by using Excel. All statistics should not have more than 2 decimal places. All Excel outputs (such as graphs and summary statistics) for each related analysis must be fitted in one sheet. 2. To analyze the total number of items purchased, construct an ungrouped frequency distribution, graph, and find the summary statistics by each type of customer (regular/promotion). Label the graphs completely. Describe the shape of the distribution for each type of customer and discuss similarities or differences by interpreting the graphs and summary statistics. What can you conclude? 3. To analyze customer age, construct a frequency distribution, graph, and find…
As a sales analyst for the shoe retailer Foot Locker, one of your responsibilities is measuring store productivity and then reporting your conclusion back to management. Foot Locker uses sales per square foot as a measure of store productivity. While preparing your report for the second quarter results (Q2), you are able to determine that annual sales for last year ran at a rate of $406 per square foot. Therefore, $406 per square foot will be your sales estimate for the population of all Foot Locker stores during Q2. For your Q2 Sales Report, you decide to take a random sample of 64 stores. Using annual data from last year, you are able to determine that the standard deviation for sales per square foot for all 3,400 stores was $80. Therefore $80 per square foot will be your population standard deviation when compiling your Q2 report. Management has asked for the probability that your sample mean based on 64 stores is 1) within $15 and 2) within $5 of the population mean…

1. Suppose that you estimate a model of house prices to determine the impact of having beach frontage on the value of a house.14 You do some research, and you decide to use the size of the lot instead of the size of the house for a number of theoretical and data availability rea- sons. Your results (standard errors in parentheses) are: PRICE; = 40 + 35.0 LOT¡ – 2.0 AGE; + 10.0 BED; – 4.0 FIRE; (1.0) (5.0) (10.0) (4.0) (10) N = 30 R2 =.63 where: PRICE¡ =the price of the th house (in thousands of dollars) =the size of the lot of the th house (in thousands of square feet) = the age of the th house in years =the number of bedrooms in the th house =a qualitative/dummy variable for a fireplace (1 = yes for the th house) LOT; AGE; BED; FIRE; a. You expect the variables LOT and BED to have positive coefficients. Create and test the appropriate hypotheses to evaluate these expectations at the 5-percent level. b. You expect AGE to have a negative coefficient. Create and test the appropriate…
