Question

in a third - grade classroom, the number of books read by each student in one month is:
6, 7, 5, 6, 8, 7, 8, 6, 9, 7, 6, 5, 7, 6, 9
click on the line plot that shows these data.

Explanation:

Step1: Count the frequency of each number

• For \(5\): count the number of \(5\)s in \(6,7,5,6,8,7,8,6,9,7,6,5,7,6,9\). There are \(2\) fives.
• For \(6\): count the number of \(6\)s. There are \(5\) sixes.
• For \(7\): count the number of \(7\)s. There are \(4\) sevens.
• For \(8\): count the number of \(8\)s. There are \(2\) eights.
• For \(9\): count the number of \(9\)s. There are \(2\) nines.

Step2: Check each line - plot

• Analyze each line - plot based on the frequencies we just calculated (\(5:2\), \(6:5\), \(7:4\), \(8:2\), \(9:2\)).

Answer:

The line - plot with \(2\) Xs above \(5\), \(5\) Xs above \(6\), \(4\) Xs above \(7\), \(2\) Xs above \(8\) and \(2\) Xs above \(9\) is the correct one.
