Decide on the two grocery stores to use in this activity
Decide on the 15 products you want to compare.
The brand name, product, and size have to be exactly the same at each store. Therefore, do not compare generic brands as they have different names at different stores.
You may have to wait until your visit to the first store to determine the “size” as you may not be aware of the different size packages for different products.
Use a variety of products to get a good representation of all items at the stores.
At each store, record the price of each product on your list. (A question always comes up whether to use a sales prices or a club card price. You should use the price of the item that you’d pay on the particular day you visit the store.)
If you didn’t record the prices in an electronic spreadsheet (such as an Excel spreadsheet) at each store, do so after you collect all your data.
Questions to answer after collecting your data
The question of interest is, “Are the items at one of the two grocery stores in your study more expensive, on average, than the other store?”
Answer these questions to answer the question of interest. (R tutorial 2 may be helpful in answering some of these questions.)
1. (1 point) Give the two stores you are comparing and a personal motivation on why you chose those two stores.
2. (2 points) Give a brief summary of how you chose the 15 items you used in the study. Do you feel these items are representative of all items at the store? (In other words, do you feel that you’ll be able to answer the question of interest based the items in your sample?) Why or why not?
3. (3 points) What method of inference you used and why? (Include a check of the conditions to use that particular method. If you use a graph to assess any condition, include the graph) (Hint: think about the samples you took – are the samples independent or dependent?)
4. (3 points) State the null and alternative hypotheses in statistical notation. Define any parameters used.
5. (2 points) Obtain and include an appropriate graphical display that will allow you to make an initial guess as to whether you feel the null hypothesis will be rejected or not. (Hint: think about what method you will be using to perform the hypothesis test.) Comment on whether or not you feel the null hypothesis will be rejected and why or why not.
6. (1 point) Perform the analysis in R. Report the test-statistic (with degrees of freedom) and p-value.
7. (3 points) State a conclusion in the context of the problem that answers the question of interest supported with the p-value obtained in #6.
8. (3 points) Use R to construct a 95% confidence interval for the average difference in prices between the two stores. Include and interpret the confidence interval in the context of the problem. (3 pts)
9. (2 points) Which store would you shop at? Why?
10. (2 points) Provide a copy of your data.
