Question

interpreting a histogram
use the drop-down menus to answer the questions.
what do the numbers on the left, or y-axis, represent?
how many students spent 2 or more hours studying?
how many students spent fewer than 2 hours a night studying?
histogram: time students spent studying, x-axis: hours (0–0.59, 1–1.59, 2–2.59, 3–3.59, 4–4.59), y-axis: students (0–8). bars: 0–0.59: 3, 1–1.59: 5, 2–2.59: 7, 3–3.59: 4, 4–4.59: 1. drop-down for fewer than 2 hours: options 3,5,8,15

Explanation:

Step1: Identify y - axis label

The y - axis is labeled "Students", so the numbers on the y - axis represent the number of students.

Step2: Calculate students who spent 2 or more hours

The bars for \(2 - 2.59\), \(3 - 3.59\), and \(4 - 4.59\) hours. The heights are \(7\), \(4\), and \(1\) respectively.

$$7 + 4+1=12$$

Step3: Calculate students who spent fewer than 2 hours

The bars for \(0 - 0.59\) and \(1 - 1.59\) hours. The heights are \(3\) and \(5\) respectively.

$$3 + 5=8$$

Answer:

What do the numbers on the left, or y - axis, represent? Number of students.
How many students spent 2 or more hours studying? 12.
How many students spent fewer than 2 hours a night studying? 8.
