Question

A study was undertaken to see now accurate rood labeling for calories on rood that is considered reduced calorie. The group measured the amount of calories for each item of food and then found the percent difference between measured and labeled food. The group also looked at food that was nationally advertised, regionally distributed, or locally prepared. The data is in the table. Do the data indicate that at least one of the mean percent differences between the three groups is different from the others? Test at the 10% level. Percent Differences Between Measured and Labeled Food National Advertised Regionally Distributed Locally Prepared -14 54 48 -14 -5 122 3 26 15 -11 6 140 -0 28 163 12 12 21 -21 3 235 -10 37 80 -4 26 7 23 11 48 5 45 -5 -3 -12 2 12 -3 -3 3 State the hypotheses.
