question 100

Multiple Choice

Solve the problem.
-The table shows the number of households burglarized in a sample of households with dogs and in a sample of households without dogs. Assume that you plan to use a significance level of $\alpha = 0.01$ 01 to test the claim that $\mathrm { p } _ { 1 } < \mathrm { p } _ { 2 }$ . Find the critical value(s) for this hypothesis test. Do the data support the claim that a smaller
Proportion of households with pet dogs are burglarized? $$\begin{array} { l c c } \hline & \text { Household with Dog } & \text { Household without Dog } \\\hline \text { Number of households in sample } & 208 & 126 \\\text { Number of households burglarized } & 21 & 15 \\\hline\end{array}$$
