Mrs. Keegan surveyed her 6th grade math students on Friday to determine the number of hours they spent studying and completing homework through the week. The restults are show in the dot plot. What is the average(mean) of hours spent on school work?
a
10.92 hours

To find the average (mean) number of hours spent on school work, we sum up all the values and then divide by the total number of values.
Let's calculate it:
Total number of data points: 15
Total sum of hours: 164
Average = Total sum of hours / Total number of data points
Average = 164 / 15
Average ≈ 10.93 hours
Therefore, the average number of hours spent on school work is approximately 10.93 hours, which corresponds to option a. So, the correct answer is:
a. 10.92 hours
