## Video Game Usage Among College Freshmen### Research ContextIn a study involving 200 college freshmen, participants were asked how many hours per week they spent playing video games. The results were summarized in the following frequency distribution table:| Number of Hours | Frequency ||-----------------|-----------|| 1.0-5.9 | 28 || 6.0-10.9 | 31 || 11.0-15.9 | 44 || 16.0-20.9 | 29 || 21.0-25.9 | 20 || 26.0-30.9 | 18 || 31.0-35.9 | 12 || 36.0-40.9 | 8 || 41.0-45.9 | 9 || 46.0-50.9 | 1 |### Analysis Questions**Part 1 of 2**(a) **How many classes are there?**- There are **10** classes.(b) **What is the class width?**- The class width is **5**.**Part 2 of 2**Note: Do not round.(c) **What percentage of students play video games for less than 46 hours per week?**- \(\_\_\%\) of the students play video games for less than 46 hours per week.(d) **What percentage of students play video games for 41 or more hours per week?**- \(\_\_\%\) of the students play video games for 41 or more hours per week.
