QDES.B A study was undertaken to see how accurate food labeling for calories on food 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 following table ("Calories datafile," 2013).  Table:  Percent Differences Between Measured and Labeled Food National Advertised Regionally Distributed Locally Prepared 2 41 15 -28 46 60 -6 2 250 8 25 145 6 39 6 -1 16.5 80 10 17 95 13 28 3 15 -3   -4 14   -4 34   -18 42   10     5     3     -7     3     -0.5     -10     6       Do the data indicate that at least two of the mean percent differences between the three groups are different?…
