At the ? = 0.05 level of significance, test for any difference in the job satisfaction among the four professions. H0: μL ≠ μPT ≠ μC ≠ μSA Ha: μL = μPT = μC = μSA H0: At least two of the population means are equal. Ha: At least two of the population means are different. H0: μL = μPT = μC = μSA Ha: Not all the population means are equal. H0: μL = μPT = μC = μSA Ha: μL ≠ μPT ≠ μC ≠ μSA H0: Not all the population means are equal. Ha: μL = μPT = μC = μSA Find the value of the test statistic. (Round your answer to two decimal places.) =_____ Find the p-value. (Round your answer to three decimal places.) p-value = ______ State your conclusion. (A) Do not reject H0. There is not sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions. (B) Reject H0. There is not sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions. (C) Reject H0. There is sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions. (D) Do not reject H0. There is sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions.
A research study concluded that self-employed individuals do not experience higher job satisfaction than individuals who are not self-employed. In this study, job satisfaction is measured using 18 items, each of which is rated using a Likert-type scale with 1–5 response options
