Question

Use the following information to answer the next two exercises: Table $1.38$contains data on hurricanes that have made direct hits on the U.S. Between $1851$and $2004$. A hurricane is given a strength category rating based on the minimum wind speed generated by the storm.

What is the relative frequency of direct hits that were category 4 hurricanes?

a. $0.0768$

b. $0.0659$

c. $0.2601$

d. Not enough information to calculate

Short answer

The relative frequency of direct hits for $4$hurricanes is$0.0659$

Step-by-step solution

Given information

The number of direct hits for $4$hurricanes is $18$and the total number of direct hits is$273$

Explanation

$$\begin{gathered} \text{Relativefrequency}=\frac{Numberofdirecthitsfor4hurricanes}{Totalnumberofdirecthits} \\ \text{=}\frac{18}{273} \\ \text{=0.0659} \end{gathered}$$
