Statistics Discussions Please provide a 250-300 word explanation for the below discussion questions and please include APA style in-text quotation marks, citations, and references!!

However in most studies we do we cannot say that one variable (ad spending) causes the other (sales). Why not? What has to be the case for us to discuss one variable "causing" another? Statistics Discussion Week V Class Project By the end of this week you should know which statistics test you will be using for your project. In this week's discussion I want the class to determine which test you think you should be using and why for your project. I will keep an eye on the discussion to make sure it is going in the right direction. Hint...there is a reason you are doing this discussion this week. (Below is the upcoming project criteria). Class project-I will submit this for completion assignment later!!!! *** The purpose of the Class Pricing Project is for you to determine if the prices at one retail establishment are lower or higher than another retailer. You will need to compare the prices of at least 30 items (minimum sample size) at two different retailers to see if there is a statistically significant difference between the prices of the two retailers. Be sure the 30 items are exactly the same items (product, brand) sold by each retailer. For an outline of the project, follow the Steps in the Process of Hypotheses Testing that starts on page 177 of your Ravid and Haan text. Be sure to explain how you calculated your statistical test. You can do the calculations by hand or can use software (i.e., SPSS, Excel). If you did the calculations by hand show the calculations as part of your report. If you do the calculations by software, include your output in the report. The Class Pricing...
