# Evaluate Statistical Analyses

This week, you have learned about t-tests and ANOVA and will apply what you have learned in the evaluation of several research scenarios.

After the last word is presented, all participants are instructed to recall as many words as possible by writing them on a blank sheet of paper. All participants are given 10 minutes to recall the words. Provide the appropriate null and alternative hypotheses. Indicate which type of analysis would be appropriate to answer this research question. Be specific and support your answer using the textbook or other course materials. Name the independent and dependent variables used in the analysis. What are the levels of the independent variable? Indicate the levels of measurement for each variable. Describe the Type I error for this study. Describe the Type II error for this study Research Scenario 3 A local manufacturing company is interested in determining whether their employees are as happy with their jobs as other employees. The manufacturing company asked the workers, who volunteered to participate, to rate their happiness at work on a scale from 1 to 10 where 1 was not at all happy and 10 was extremely happy. The manufacturing company found that the mean happiness rating for their employees is 7.3. In the general population of workers in the United States, the mean happiness rating is 6. Provide the appropriate null and alternative hypotheses. Determine which type of analysis would be appropriate to answer this research question. Be specific. Please support your answer using the textbook or other course materials. Name the variables used in the analysis. What are the levels of measurement for each variable? Describe the Type I error for this study. Describe the Type II error for this study
