Question

the train conductor made sure to count the number of passengers on each train. which range of passengers per train occurred least frequently? 0 - 19 passengers 20 - 39 passengers 40 - 59 passengers 120 - 139 passengers

Explanation:

Step1: Analyze the bar heights

The vertical axis represents the number of trains (frequency). The shorter the bar, the less frequent the passenger range.

Step2: Compare the frequencies

• For \(0 - 19\) passengers: The bar height is \(2\).
• For \(20 - 39\) passengers: The bar height is \(5\).
• For \(40 - 59\) passengers: The bar height is \(3\).
• For \(120 - 139\) passengers: The bar height is \(3\).

Since \(2<3 < 5\), the \(0 - 19\) passengers range has the smallest frequency.

Answer:

\(0 - 19\) passengers.
