Question

Hypothesis Testing with Chi-Square Goodness of Fit (Null = Equality) The college is planning to add a food vendor in the student union and would like to know what type of foodservice the students would prefer. A sample of n = 120 students is obtained and each student is asked to select his/her preference from a coffee shop, a pizza place, or a hamburger grill. Do the data indicate any significant (? = .05) differences in preference among the three types of foodservice? Observed Frequencies Coffee 53, Pizza 37, Hamburger 30 Expected Frequencies Coffee 40, Pizza 40, Hamburger 40 What is the decision and conclusion for this study (Step 4)? Fail to reject the null hypothesis. Results suggest there is a significant relationship between foodservice vendor and preference. Reject the null hypothesis. Results suggest the three food vendors are not equally preferred in the population. Reject the null hypothesis. Results suggest the three food vendors are equally preferred in the population. Reject the null hypothesis. Results suggest there is a significant relationship between foodservice vendor and preference. Fail to Reject the null hypothesis. Results suggest the three food vendors are equally preferred in the population.
