Cheddar Cheese Consumption A consumer group claims that the mean annual consumption of cheddar cheese by a person in the United States is
at most 10.3 pounds. A random sample of 100 people in the United States
has a mean annual cheddar cheese consumption of 9.9 pounds. Assume the
population standard deviation is 2.1 pounds. At a = 0.05, can you reject the
claim? (Adapted from U. S. Department of Agriculure)

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
