Mary's Burger is a family-run fast food joint. In addition to its famous hamburger, Mary's Burger has just launched a new "Organic Beef burger. The owner, Mary, would like to know if her customers like the new organic beef burger so she did some research. She asked 10 customers to taste a placebo, 10 customers to taste the regular burger, and another 10 customers to taste the organic beef burger. She asked the customers to rate on a likert scale from 1 (not delicious) to 7 (very delicious). That is, the higher the score, the better the hamburger tastes. Mary then run some data analysis using the ANOVA procedure in SPSS and the output table was shown below.
