Chapter 1, Problem 6E(choose chapter or problem)
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.
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?

QUESTION:
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.
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?
ANSWER:
Solution 6E
Step1 of 4:
Let us consider a relative frequency Histogram it presents number of quarts of milk that had been purchased the previous week:
Here our goal is:
a). We need to determine the number of quarts of milk purchased by the largest proportion of the 25 families by using this relative frequency histogram.
b). We need to find the proportion of the 25 families purchased more than 2 quarts of milk.
c). We need to find the proportion purchased more than 0 but fewer than 5 quarts.
Step2 of 4:
a).
From the above given Relative frequency Histogram we can say that more number of people falls under 2 quarts modal category. Therefore 9 out of 25 people falls in this category.
