Information A group of business executives is interested in comparing the job satisfaction among lawyers, physical therapists, Flag cabinetmakers, and system analysts. They chose random samples of 10 workers from each of the 4 professions (so 40 question individuals in total) and asked them to rate their job satisfaction on a scale from 0-100. Question 15 Explain why one-way ANOVA would be the most appropriate method to use out of all the methods we have learned in Not yet answered MATH2209. Clearly refer to the response variable and explanatory variable in your answer. Marked out of 2.00 1 A B I Flag question Question 16 Is there evidence of a difference in the average job satisfaction for the different professions. Answer this question by Not yet indicating which of the following conclusions is the most appropriate, given that the assumptions were checked and are answered all met, and test statistic is F = 4.91, with a p-value of 0.006. Marked out of 2.00 O a. Since the assumptions are met, we can conclude that there is a difference in the mean job satisfaction rating for Flag the population of all people in these four professions. question O b. Since the assumptions are met, we have strong evidence (p = 0.006) that there is a difference in the mean job satisfaction rating for the population of all people in these four professions. O c. Since the assumptions are met, we cannot conclude that there is a difference in the mean job satisfaction rating for the population of all people in these four professions. O d. Since the assumptions are met, we have strong evidence that there is not a difference in the mean job satisfaction rating for the population of all people in these four professions.Question 17 Not yet answered Marked out of 1.00 F Flag question Question 1 8 Not yet answered Marked out of 4.00 F Flag question Now, we want to look a little closer at where there might be a difference. How many pairwise comparisons do we need to consider? Answer: Interpret the second Tukey confidence interval on the output in the context of the problem. This is the interval comparing Cabinetmakers to Lawyers (calculated as Cabinet Makers - Lawyers). 1AVBIEEETSE
