Do you reject or fail to reject the null hypothesis?
You have been hired by one of the local pizza places in my town that is trying to determine which type of sauce customers like the most. There are three types of sauces it is currently using: regular tomato sauce, spicy tomato sauce, and white sauce. You asked 16 customers to taste and rate each type of sauce, using a 1 (hated it) to 7 (loved it) response range. Here are the means for each type of sauce:
Sauce Mean
Regular tomato 4.33
Spicy tomato 6.12
White 2.25
Ans: reject the null hypothesis
