Chapter 10.6, Problem 49CCR

a.

To determine

To find:To describe the data.

Answer to Problem 49CCR

The majority of states have less than $20$ roller coasters. A minority has between $20$ and $59$ roller coasters.

Explanation of Solution

Given Information: It is given that a graph which shows no. of coasters and no. of states.

The majority of states have less than $20$ roller coasters. A minority has between $20$ and $59$ roller coasters. One state has between $70and79$ roller coasters.

b.

To determine

To find: There a jagged line in the vertical axis

Answer to Problem 49CCR

The jagged lines represents a ‘cut’ in the y-axis. The first bar would actually be $3$ times larger than the second.

Explanation of Solution

Given Information:: It is given that a graph which shows no. of coasters and no. of states.

The jagged lines represents a ‘cut’ in the y-axis. The first bar would actually be $3$ times larger than the second. This is done to solve space.

c.

To determine

To find: Number of states have no roller coasters.

Answer to Problem 49CCR

Number of states have no roller coasters is $30$ .

Explanation of Solution

Given Information:: It is given that a graph which shows no. of coasters and no. of states.

$30$ states are reported to have fewer than $10$ roller coasters. Any of these states might have $0$ , but it is impossible to determine the exact amount just from the graph.
