students spent 1 to 6 hours on homework.

Explanation:

• A dot - plot is indeed a simple plot with data values as dots above a number line.
• It shows the frequency (number of dots for a value) of data points in a dataset.
• The distribution (how data is spread) can be seen from the dot - plot.
• Looking at the number line in the dot - plot, the values range from 1 to 6.
• For the value 4 on the number line, there are 3 dots (so 3 students spent 4 hours).
• For the value 2 on the number line, there are 5 dots (so 5 students spent 2 hours).
