AI explanation

Using the basic average formula, the total hours spent watching television equals the sum of all reported times: 20 plus 15 plus 25 plus 10 plus 30 plus 18 plus 22 plus 12, which equals 152 hours. To find the average, divide this total sum by the number of individuals, which is 8. Dividing 152 by 8 results in an average of 19 hours.
