Average Study Hours Calculation

A statistics class conducted a survey to gather information about the number of hours students study per week. The results showed the following distribution of study hours:

0-1 hours: 5 students

2-3 hours: 10 students

4-5 hours: 15 students

6 or more hours: 8 students

Using this data, calculate the average (mean) number of hours spent studying per student.

To find the mean, use the formula:

$$ ext{Mean} =\frac{ ext{Total Study Hours}}{ ext{Total Number of Students}}$$
