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."

Question
I need help with the problems given.
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:
7, 5, 5, 2, 5, 5, 6, 2, 5, 6, 2, 8, 7, 7, 8, 9, 7, 7, 8, 7, 7, 6, 3, 7, 6,
