Use а χ2 test оf Assоciаtiоn to test the clаim that in the given contingency table, the row variable and the column variable are independent. Be sure to identify and include in your answer the following: the null hypothesis, alternative hypothesis, expected values, test statistic, rejection region, conclusion about the null hypothesis, and a final conclusion that addresses the original claim that the two variables are independent (no relationship). Note: you can use the equation editor to insert symbols and you must show some work as to how the expected values were calculated - if no work is shown full credit will not be given - you can use the insert table function to insert your work). Injection location vs Reaction: Jackson et al. (2013)[1] wanted to know whether it is better to give the diphtheria, tetanus and pertussis (DTaP) vaccine in either the thigh or the arm, so they collected data on severe reactions to this vaccine in children aged 3 to 6 years old. One nominal variable is reaction type (severe reaction vs. no severe reaction); the other nominal variable is location (thigh vs. arm). (Use α = 0.01). These data were collected[2]: No Severe Reaction Severe Reaction Thigh 26 14 Arm 64 46 [1] Jackson, L.A., Peterson, D., Nelson, J.C., et al. (13 co-authors). 2013.

Suppоse а grоup is interested in determining whether teenаgers оbtаin their drivers licenses at approximately the same average age across the country. Suppose that data are randomly collected from five teenagers in each region of the country. The numbers represent the age at which teenagers obtained their drivers licenses. An ANOVA was performed to determine whether or not significant differences exist among the mean ages for the five different regional groups. Assume α = 0.05. The partially completed ANOVA Table is located below. (worth 6 points) SS df MS F TREATMENT 4 0.22575 ERROR Total 1.7055 19 TYPE YOUR ANSWERS ONLY TO EACH STEP IN THE TEXTBOX. ALL WORK MUST BE SHOWN ON YOUR ANSWER SHEET. Complete the table above. (Use the insert table function to do so) What would be the null hypothesis in this study? (you must enter the parameters or no credit will be given for the hypotheses -- you can use the equation editor to insert symbols/Greek letters) What would be the alternate hypothesis? What is your F-critical value What is the decision rule for this test? Is there a significant difference between the groups? Why or why not? Explain and/or Show your work. Conclusion: Interpret your answer in Language of the Problem. From the ANOVA table, can you conclude if one group had an average lower age than the others?
