Answer key and explanations

B. \(2\)
On the line plot, count the X marks stacked above \(\frac{2}{4}\) inch. There are exactly \(\mathbf{2}\) X marks at that position.
C. \(3\)
Look at the line plot where \(\frac{2}{4}\) inch is marked. Count the X marks stacked above that tick: we see \(\mathbf{3}\) marks.
C. \(3\)
On the line plot, count the X marks stacked above \(\frac{2}{8}\) inch. There are \(\mathbf{3}\) X marks.
B. \(2\)
On the line plot, count the X marks stacked above \(\frac{1}{2}\) inch. There are exactly \(\mathbf{2}\) X marks.
C. \(\frac{3}{4}\) inch
On the line plot, \(\frac{1}{4}\) inch has \(2\) X marks, while \(\frac{3}{4}\) inch has \(3\) X marks. So \(\mathbf{\frac{3}{4}}\) inch has the most.
C. \(\frac{3}{8}\) inch
The shortest sticker is at \(\frac{1}{8}\) inch and the longest is at \(\frac{4}{8}\) inch. The difference is \(\frac{4}{8} - \frac{1}{8} = \mathbf{\frac{3}{8}}\) inch.
C. \(3\)
We count the measurement \(\frac{2}{4}\) inch in the data: it appears \(3\) times. So there are \(\mathbf{3}\) X marks above it.
B. \(\frac{3}{8}\) cup
Let us count: \(\frac{2}{8}\) cup appears \(2\) times, \(\frac{3}{8}\) cup appears \(3\) times, and \(\frac{4}{8}\) cup appears \(1\) time. So \(\mathbf{\frac{3}{8}}\) cup is the most common.
