Question

kelly has surveyed their 20 classmates about the number of pets in their household and received the following data:

construct a histogram:

Explanation:

Step1: Analyze the frequency distribution

We have the number of pets \(0,1,2,3,4,5,6\) with their corresponding frequencies \(2,3,4,2,2,4,3\) respectively.

Step2: Match with the histogram

In a histogram, the \(x -\)axis represents the number of pets and the \(y -\)axis represents the frequency.
For number of pets \(0\), frequency \(2\); for \(1\), frequency \(3\); for \(2\), frequency \(4\); for \(3\), frequency \(2\); for \(4\), frequency \(2\); for \(5\), frequency \(4\); for \(6\), frequency \(3\).

Answer:

The first histogram (the one in the top - left corner) is the correct one.
