QuestionThirty cars and trucks were tested by the EPA for fuel efficiency in miles per gallon ( mpg ). The frequency distribution shown here was obtained. Draw a histogram and frequency polygon for the data. \begin{tabular}{lc} Class & Frequency \\ \hline $8-12$ & 3 \\ $13-17$ & 4 \\ $18-22$ & 16 \\ $23-27$ & 5 \\ $28-32$ & 2 \\ \hline \end{tabular}

Draw a frequency histogram. Vehicles Tested for Fuel Efficiency

Studdy Solution
The histogram will visually show the distribution of fuel efficiency among the tested vehicles.
The x-axis will be labeled "Fuel Efficiency (mpg)" and range from $8$ to $32$, with intervals of $5$.
The y-axis will be labeled "Number of Vehicles" and range from $0$ to $20$, with intervals of $5$.
There will be five bars, representing the five classes of fuel efficiency, with heights corresponding to their frequencies ($3$, $4$, $16$, $5$, and $2$).
