Hypothesis Testing with the p-value Method A high school principal claims that the average senior score was at least 25 on the ACT college entrance exam. A sample list of 32 student scores are shown below. At the 0.01 level of significance, is there enough evidence to REJECT the principal's claim? 23 25 25 27 28 29 30 19 20 21 22 27 26 19 16 22 18 18 23 23 19 22 23 28 30 17 13 32 35 20 21 25 1.) Is this a hypothesis test for mean or proportion? If it's a test for mean, do we know the population standard deviation? 2.) Based on your answer in #1, which calculator will you use: A.) Mean - o Known, B.) Mean - o Unknown or C.) Proportions 3.) Will we use a Z-test ort-test? How do you know? 4.) What is the direction of the tail? Left, right or two? 5.) Complete the Hypothesis statement below with the arrows in the correct direction. Mark an X next to the claim. Claim Null Ho: (Use u for mean and p for proportion) Alternative Ha:

RECIDIVISM Report a Chi-Square test of Independence and use a 5% significance level. Explain the power of the test in words, in context. Group of answer choices The power of the test is the probability of not accepting that there is an association between Recidivism and Treatment when there actually is one. The power of the test is the probability of accepting that there is an association between Recidivism and Treatment when there is actually none. The power of the test is the probability of not accepting that there is an association between Recidivism and Treatment when there is indeed none. The power of the test is the probability of accepting that there is an association between Recidivism and Treatment when there is indeed one.
