True/False

TABLE 12-12
Recent studies have found that American children are more obese than in the past. The amount of time children spent watching television has received much of the blame. A survey of 100 ten-year-olds revealed the following with regards to weights and average number of hours a day spent watching television. We are interested in testing whether the average number of hours spent watching TV and weights are independent at 1% level of significance.
$$\begin{array} { l | c l l | r } & {\quad\quad \text { TV Hours } } & \\\text { Weights } & 0 - 3 & 3 - 6 & 6 + & \text { Total } \\\hline \text { More than } 101 \mathrm { ls } \text {. overweight } & 1 & 9 & 20 & 30 \\\text { Within } 101 \mathrm { bs } \text {. of normal weight } & 20 & 15 & 15 & 50 \\\text { More than } 10 \mathrm { lbs } \text {. underweight } & 10 & 5 & 5 & 20 \\\hline \text { Total } & 31 & 29 & 40 & 100\end{array}$$
