Answer 1

To calculate the total amount of hours played, the number of friends surveyed, and the mean number of hours played, let's go through the steps:

1. **Total hours played**:
- Jack: 3.5 hours
- Mike: 6.25 hours
- Adam: 3 hours
- Jim: 2.5 hours
- Marty: 7 hours
- Ben: 6.75 hours

Now, sum these values:
\[
3.5 + 6.25 + 3 + 2.5 + 7 + 6.75 = 29
\]

2. **Number of friends surveyed**:
There are 6 friends: Jack, Mike, Adam, Jim, Marty, and Ben.

3. **Mean number of hours played**:
To find the mean, divide the total hours played by the number of friends surveyed:
\[
\text{Mean} = \frac{\text{Total hours}}{\text{Number of friends}} = \frac{29}{6} \approx 4.83
\]

So, to answer your questions:
- **Total hours played**: 29 hours
- **Number of friends surveyed**: 6
- **Mean number of hours played**: approximately 4.83 hours
