If the null hypothesis is rejected, we would recommend Yoplait’s Research and Development department to start developing new flavors and products utilizing Greek yogurt. If the null hypothesis is not rejected, we would recommend Yoplait to focus instead on creating a better marketing campaign so as to create a demand for its present line up of Greek products. All data gathered in this survey are interval measures. The respondents were asked the question: What factors do you consider in purchasing Greek yogurt?

They were then asked to rate three factors: variety of flavors, amount of calories in each product and the price of the product, where 1 is the least important factor and 5 is the most important factor. Based on table 1 above, we can see that the average age of respondents is 27 years old. Standard deviation is pretty high at 7.7, which meant that some of the respondents were much younger and much older than the average age. In the case of the factors considered by customers in purchasing Greek yogurt, the average rating for the variety of flavors is 4.

4, amount of calories is 3.7 and price of product is at 4.0. From these rating we can already see that most respondents consider the variety of flavors the most in deciding which yogurt brand to choose. Standard deviation was 0.115475 for variety of flavor responses, 0.17266 for amount of calories responses and 0.175345 for price of product responses. 3. For the purpose of this study, we will use a single factor ANOVA because the responses of the respondents were numerical, but they were in fact categories of responses.

We cannot use the t-test or z-test because we are not looking for actual increases in sales. For this study, we will use α=.05, and we will test at 95% confidence level. We are also using a one-tailed test because we only want to know if adding more flavors will increase sales for Greek yogurt. One tailed tests are always directional
