the percentage of drivers who are at least 55 and younger than 75 is
(type a whole number.)

Explanation:

Step1: Understand the percentile concept

Percentile \(P\) means that \(P\%\) of the data is less than or equal to the corresponding value.

Step2: Find the relevant percentiles

For age \(55\), the percentile is \(79\). For age \(75\), the percentile is \(97\).

Step3: Calculate the percentage

The percentage of drivers who are at least \(55\) and younger than \(75\) is \(97 - 79=18\)

Answer:

\(18\)
