Question

Suppose 3 people out of a total of 3,026 people had an auto accident in the last 10 years. What is an estimate of the percentage of the people who had an auto accident in the past 10 years?

Answer 1

Given: That 3 people out of a total of 3,026 people had an auto accident in the last 10 years

To Determine: An estimate of the percentage of the people who had an auto accident in the past 10 years

Solution

The percentage of any event is given as

`\begin{gathered} P=(x)/(n)*100\% \\ P=percentage \\ x=number\text{ of the event} \\ n=total\text{ number of all events} \end{gathered}`

Apply the formula to given

`\begin{gathered} x=3 \\ n=3026 \\ P=(3)/(3026)*100\% \\ P=0.099\% \\ P\approx0.1\% \end{gathered}`

Hence, an estimate of the percentage of the people who had an auto accident in the past 10 years is 0.1 %
