For a statistics assignment, Shayna randomly surveyed students on how many hours per week they spend playing online games:

Answer 1

Here are the results of the survey:

- 3 students reported playing for 5 hours per week
- 7 students reported playing for 10 hours per week
- 5 students reported playing for 15 hours per week
- 4 students reported playing for 20 hours per week
- 1 student reported playing for 25 hours per week

Overall, the average number of hours per week that students spend playing online games is calculated as follows:

((3*5) + (7*10) + (5*15) + (4*20) + (1*25)) / (3+7+5+4+1) = (15 + 70 + 75 + 80 + 25) / 20 = 265 / 20 = 13.25 hours per week.

Therefore, the average number of hours per week that students spend playing online games is 13.25 hours.
