Question

a group of 6 students was asked, \how many hours did you watch television last week?\ here are their responses: 12, 7, 9, 6, 10, 11. find the mean number of hours for these students. if necessary, round your answer to the nearest tenth.

Explanation:

Step1: Sum the data values

The data points are 12, 7, 9, 6, 10, 11. We sum them: $12 + 7 + 9 + 6 + 10 + 11$. Calculating that: $12+7 = 19$, $19+9 = 28$, $28+6 = 34$, $34+10 = 44$, $44+11 = 55$.

Step2: Divide by the number of data points

There are 6 students, so we divide the sum by 6: $\frac{55}{6} \approx 9.2$ (rounded to the nearest tenth).

Answer:

9.2
