Chapter 1.2, Problem 6E

The relative frequency histogram given next was constructed from data obtained from a random sample of 25 families. Each was asked the number of quarts of milk that had been purchased the previous week.

Chapter 1.2, Problem 6E, The relative frequency histogram given next was constructed from data obtained from a random sample

a Use this relative frequency histogram to determine the number of quarts of milk purchased by the largest proportion of the 25 families. The category associated with the largest relative frequency is called the modal category.
b What proportion of the 25 families purchased more than 2 quarts of milk?
c What proportion purchased more than 0 but fewer than 5 quarts?
