TABLE 12-12
Recent Studies Have Found That American Children Are

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.
$\begin{array}{l|ccc|r} & {\text { TV Hours }} & \\\text { Weights } & 0-3 & 3-6 & 6+ & \text { Total } \\\hline \text { More than 10 lbs. Overweight } & 1 & 9 & 20 & 30 \\\text { Within 10 lbs. of normal weight } & 20 & 15 & 15 & 50 \\\text { More than 10 lbs. underweight } & 10 & 5 & 5 & 20 \\\hline \text { Total } & 31 & 29 & 40 & 100\end{array}$

-Referring to Table 12-12, which of the following statements is correct?

A) We can reject the null for any level of significance greater than 0.005.
B) We can accept the null for any level of significance greater than 0.005.
C) We can accept the null for any level of significance smaller than 0.005
D) We can reject the null for any level of significance smaller than 0.005.
