1. Research question: Is the proportion of all college students who would prefer to take a course that uses open-educational resources (OER) greater than 0.8? Data were collected from a random sample of 100 students. In that sample, 90 students said they would prefer to use open-educational resources. A researcher is planning to use this research question and these data to conduct a randomization test. What is the expected mean of their randomization distribution? 0.04 0.16 0.8 0.9 2. A two-tailed randomization test was conducted for the difference in two means. The pvalue was 0.041 for the test. At the 0.05 alpha level, should we reject or fail to reject the null hypothesis? Reject the null hypothesis Fail to reject the null hypothesis Ho: p = .1 Ha: p > .1 3. A randomization test was conducted using the hypotheses above. The p value was 0.177 for that test. At the standard 0.05 alpha level, what is the correct conclusion? There is evidence that the population proportion is greater than 0.10 There is not evidence that the population proportion is greater than 0.10 C There is evidence that the population proportion is equal to 0.10
