15. Suppose the P-value for testing hypotheses was computed to be 0.057. Which of the following statements is correct? e we can reject the null hypothesis at a = 0.10 but not at 0.05 or 0.01 b) we can reject the alternative hypothesis at a = 0.01 and 0.05 but not at 0.10 c) we can reject the alternative hypothesis at a = 0.05 and...

Researchers conducted a follow-up study predicting the outcomes of races in the House of Representatives with 189 correct predictions out of 279. Using a simulation and the 25D method, the 95% confidence interval is (0.62, 0.74) and using a theory-based approach, the 95% confidence interval for these data is (0.62,0.73). When comparing the 25D method and theory...

Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person randomly selected 100 checks and recorded the cents portions of those checks. The table below lists those cents portions categorized according to the ated values Use a 0.10 significance level to test the claim that the four categories are equally likely. The person expected that many checks for whole dollar amounts would result in...
