# Lesson 3

Interpreting Histograms

### Problem 1

Match histograms A through E to dot plots 1 through 5 so that each match represents the same data set.

### Problem 2

Here is a histogram that summarizes the lengths, in feet, of a group of adult female sharks. Select all the statements that are true, according to the histogram.

A:

A total of 9 sharks were measured.

B:

A total of 50 sharks were measured.

C:

The longest shark that was measured was 10 feet long.

D:

Most of the sharks that were measured were over 16 feet long.

E:

Two of the sharks that were measured were less than 14 feet long.

### Problem 3

This table shows the times, in minutes, it took 40 sixth-grade students to run 1 mile.

time (minutes) frequency
4 to less than 6 1
6 to less than 8 5
8 to less than 10 13
10 to less than 12 12
12 to less than 14 7
14 to less than 16 2

Draw a histogram for the information in the table.

### Solution

Order these numbers from greatest to least: $$\text-4$$, $$\frac14$$, 0, 4,  $$\text{-}3\frac{1}{2}$$, $$\frac74$$, $$\text{-}\frac{5}{4}$$
