Answer 1

To find the percentage of 8th graders who estimated they spend less than an hour a day on social media, we first need to find the total number of 8th graders surveyed and then the number who said they spend less.

From the data provided:

- 8th graders who spend **Less** than an hour = 14
- 8th graders who spend **More** than an hour = 17

Now, let's calculate the total number of 8th graders surveyed:

\[
\text{Total 8th graders} = \text{More} + \text{Less} = 17 + 14 = 31
\]

Next, we need to find the percentage of 8th graders who estimated they spend less than an hour:

\[
\text{Percentage} = \left( \frac{\text{Number of 8th graders spending less}}{\text{Total number of 8th graders}} \right) \times 100
\]

\[
\text{Percentage} = \left( \frac{14}{31} \right) \times 100 \approx 45.16
\]

Rounding to the nearest whole number gives us:

\[
\text{Percentage} \approx 45\%
\]

Thus, the final answer is:

**45%**.
