problem using the critical region method of testing (i.e., traditional method). (Round your answers to three decimal places.) test statistic \( = \) critical value \( =\pm \) State your conclusion in the context of the application. Reject the null hypothesis, there is insufficient evidence that the drug has changed the mean \( \mathrm{pH} \) level. Fail to reject the null hypothesis, there is sufficient evidence that the drug has changed the mean pH level. Reject the null hypothesis, there is sufficient evidence that the drug has changed the mean pH level. Fail to reject the null hypothesis, there is insufficient evidence that the drug has changed the mean pH level. Compare your conclusion with the conclusion obtained by using the \( P \)-value method. Are they the same? We reject the null hypothesis using the \( P \)-value method, but fail to reject using the traditional method. We reject the null hypothesis using the traditional method, but fail to reject using the \( P \)-value method. The conclusions obtained by using both methods are the same.
