Question

The given table shows the time five swimmers spent in the pool. Select the option that shows the correct line plot for the given information.
$\begin{array}{cc}\text{Swimmers}& \text{Time (in hours)}\\ \text{A}& \frac{1}{3}\\ \text{B}& \frac{1}{2}\\ \text{C}& \frac{1}{4}\\ \text{D}& \frac{1}{3}\\ \text{E}& \frac{1}{4}\end{array}$

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Number of swimmers who spent $\frac{1}{4}$ of an hour in the pool $=2$ (Swimmers C and E)
Number of swimmers who spent $\frac{1}{3}$ of an hour in the pool $=2$ (Swimmers A and D)
Number of swimmers who spent $\frac{1}{2}$ of an hour in the pool $=1$ (Swimmer B)
Using one dot to represent one swimmer and marking their time on the horizontal axis, we get
