I will try wording this question a different way since I did not get an answer to my last tutor question.

The homework problem and questions are as follows: I did not put the data table in this question as I cannot figure out how to make it load properly. However, I think I have provided enough information for my question to be answered.

Problem : WinCo Foods, a large Discount grocery retailer in the western United States, promotes itself as the lowest priced grocery retailer. In newspaper ads WinCo Foods published a price comparison for products between WinCo and several competing grocery retailers. One of the retailers compared against WinCo was Walmart, also known as a low-price competitor. WinCo selected a variety of products, listed the price of the product charged at each retailer, and showed the sales receipt to prove the prices at WinCo were the lowest in the area. A sample of the products and their prices comparison at both WinCo and Walmart are shown in the following table:

This was my answer for the null and alternative hypothesis.The mean value of winco was 2.3 and the mean value of Walmart was 2.74.. so, my question is am I correct in accepting the alternative hypothesis versus the null hypothesis?Where the mean price of winco (u1) is less than the mean price of Walmart (u2)

My Answers

1. What is the null and alternative hypothesis to the case above?

Null Hypothesis = H0: 1 > 2

Alternative Hypothesis = HA: 1 < 2

2: What is the conclusion of your analysis? The conclusion of the analysis is that the mean price of Winco is less than the mean price of Walmart.I reject the Null Hypothesis and accept the Alternate Hypothesis

Are my answers valid?
