To determine the mean number of hours students spent on math homework, we need to calculate the average of the given data points.
The given options are: 1.4 hours, 9 hours, 2.14 hours, and 1 hour.
To find the mean, we sum up all the data points and divide by the number of data points.
(1.4 + 9 + 2.14 + 1) / 4 = 13.54 / 4 ≈ 3.39.
Therefore, the mean number of hours students spent on math homework is approximately 3.39 hours.
The graph shows the number of hours randomly selected students spent on math homework.
