Continuing the analysis of previous job tenure in business, finance and administration, we will now investigate if the mean job tenure is dependent on educational attainment. Collect data on the previous job tenure for Canadians who meet the following conditions: between 30 and 44 years of age, either "Unemployed" or "Not in labour force, and belonging to Business, finance and administration" occupations. Once you have filtered the data, sort by highest educational attainment. Specifically, focus on three highest educational attainment categories: high school graduate, postsecondary certificate or diploma, and bachelor's degree. a) Perform at the 10% significance level the one-way ANOVA test to compare the population mean previous job tenure among the three educational attainments, assuming that all of the test requirements are met. Should we reject or not reject the claim that there is no difference in population mean job tenure between educational attainments? b) Provide a possible explanation for the difference you did or did not observe in mean job tenure between the educational attainments in part a).
