Well, the sample mean, which we would denote by lowercase x with a bar over it, it's just the sum of all of these divided by the number of data points we have. So let's see, we have 1.5 plus 2.5 plus 4 plus 2 plus 1 plus 1. And all of that divided by 6, which gives us, see, the numerator 1.5 plus 2.5 is 4. Plus 4 is 8. Plus 2 is 10. Plus 2 more is 12. So this is going to be 12 over 6, which is equal to 2 hours of television.
