Solutions for Open Responses

9) The test statistic, LaTeX: z_{\hat{p}}=1.98, is greater than the critical value LaTeX: z_{\alpha}=1.645, and is therefore in the rejection region. Also, the P-value, .0239, is less than the significance level, LaTeX: \alpha=0.05.

10) The data supports the claim that the Democrat won.

11) Yes, with LaTeX: \alpha=0.01, LaTeX: z_{\alpha}=2.33, and LaTeX: z_{\hat{p}} would no longer be in the rejection region. Similarly, the P-value would now be greater than alpha.

 

20) LaTeX: z_{\hat{p}}>LaTeX: z_{\alpha}, so is not in the rejection region. P-value is greater than alpha

21) There is not enough data to support the claim that less than 5% of the games are defective.

22) It would not. The P-value would still be greater than alpha, and the test statistic would still be outside the rejection region.
