(1) Using StatCrunch and the Online Seller Data provided on Blackboard, find and report the following summary statistics, representing both measures of center (e.g., mean and median) and measures of variation/spread (e.g., standard deviation and range): (i) The mean and median for Amazon.com product prices. (ii) The mean and median for Walmart.com product prices. (iii) The standard deviation and range for Amazon.com product prices. (iv) The standard deviation and range for Walmart.com product prices.

(2) Using the StatCrunch results obtained in Part (1), state initial/preliminary conclusions that could be made in two to four complete sentences.

(3) Using StatCrunch and the Online Seller Data provided on Blackboard, create a statistical graph that can be used to compare the product prices for Amazon.com and Walmart.com. (i) Provide the statistical graph(s) created. (ii) In two to four complete sentences, state initial/preliminary conclusions that could be made. *Note: Any conclusions made up to this point have been initial and do not suggest statistical significance yet, as no formal statistical testing or other inferential procedure such as confidence interval estimation has been performed. You will need to move beyond summary statistics and beyond visualizations for Part (4) below!

(4) One research question that could be posed using the available data: Do product prices differ significantly between Amazon.com and Walmart.com and, if so, by how much? Determine a method that would be appropriate for answering this research question. Using StatCrunch and the available data, perform the statistical procedure deemed appropriate. Hint: You will need to go beyond the exploratory data analysis (i.e., summary statistics and visualizations) in Questions 1-3 above. (i) What method did you use to answer the research question e.g., One-Sample t-Test for Means? (ii) Why did you select this particular method to answer the research question? (iii) In one to two complete sentences, summarize and interpret the relevant findings of your analysis in the context of the research question i.e., what do the findings suggest about the impact of online retailer on product prices? (iv) Consider and, then, suggest how you would approach data collection in the future if you were interested in comparing Amazon.com and Walmart.com product prices for one particular market sector/category within online sales (e.g., Grocery/Cosmetic) during fall 2020.
