Noodles and Company tested consumer reaction to two spaghetti sauces. Each of 70 judges rated both sauces on a scale of 1 (worst) to 10 (best) using several taste criteria. To correct for possible bias in tasting order, half the judges tasted Sauce A first, while the other half tasted Sauce B first. Actual results are shown below for “overall liking.” Sauce A:
6, 6, 7, 5, 5, 1, 7, 6, 5, 7, 5, 1, 8, 7, 7, 5, 7, 5, 6, 7, 8, 3, 6, 9, 7,
