Per the instructor….thank you for what you’ve done so far. I have one BIG glaring hole in your paper that I am unable to resolve from what you wrote. Let me share that with you: In Table 2, you report p values for the “before” and “after” values. This is before your hypothesis test, so I’m wondering what you’re doing there to generate those values. What is the null hypothesis and alt hypothesis? When you announce those values, there should be some indication where they come from (work shown). The second MAJOR question I have for you is this: In that same Table 2, you say those are not significant, and later on, you say you cannot reject your null hypothesis. But you conclude by saying “There is weak evidence that there is a significant relationship between the difference in satisfaction ratings before and after the brand name change”. Which is it? You can’t really claim both. One thing that jumped out at me early was you using the term “correlation”, and as often as you did. In the first page, you say you used a descriptive correlational technique”. In statistics, that term means something pretty specific. You don’t have two variables, and so I don’t think you’re doing a correlation. Let me say a few things about that assignment. The only variable is the actual scores. You are required to do a hypothesis test because of this language: “Determine whether there is a difference in customer satisfaction ratings before and after the brand name change.” Whether you treat this as pairs of data, and work with both the original mean and the new mean, or if you treat the pairs as forming a single piece of data (change in scores), your null hypothesis is that the average change is not statistically significantly different from 0. Your calculations should verify that it’s not significantly different from 0, and you go on. I’m available for more questions, or if you just want to talk about the assignment (glege@umassglobal.edu). Thanks,Jerry
