4. Emma is keeping track of how many hours per day she watches television. The bar graph below shows the results.

Question

What is the average amount of time Emma watches television each day? Round to the nearest hour.

4 hours
23 hours
2 hours
24 hours

Answer 1

To find the average amount of time Emma watches television each day, we need to calculate the mean of the data given in the bar graph.

By summing up the values on the graph, we have:
4 + 23 + 2 + 24 = 53 hours

Then, we divide the total by the number of data points (in this case, 4) to find the average:
53 / 4 = 13.25 hours

Rounded to the nearest hour, the average amount of time Emma watches television each day is 13 hours.
