Math 10 Review of Chapter 9 1. Carefully read the following questions and choose True or False for each of the following: a. A test designed with a maximum Type I error of 5% will have more power than a test designed with a maximum Type I error of 1%.
b. Type I error can only occur when the Null Hypothesis is rejected.
c. The critical value depends on α and the p-value depends on the test statistic.
d. A test with more power has a higher chance of rejecting a false Ho.
e. Sample statistics should never appear in the Null or Alternative Hypotheses.
f. If you fail to reject the Null Hypothesis, this means the Null Hypothesis is true.
g. The significance level of the test is chosen to reflect the maximum probability of making type I error the designer is willing to take.
2. Here are several proposed sets of null and alternative hypotheses. Determine if the hypotheses are valid or not valid for the models we have covered in our class. If the model is not valid, briefly explain why the model is not valid.
