Need help understanding how to work this problem. Thanks

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 ranging from strong agreement to strong disagreement. A higher score on this scale indicates a higher degree of job satisfaction. The sum of the ratings for the 18 items, ranging from 18-90, is used as the measure of job satisfaction. Suppose that this approach was used to measure the job satisfaction for lawyers, physical therapists, cabinetmakers, and systems analysts. Suppose the results obtained for a sample of 10 individuals from each profession follow. Lawyer Physical Therapist Cabinetmaker Systems Analyst 42 57 54 42 44 76 63 72 80 73 40 88 58 53 62 66 50 61 8 2 4 2 2 9 2 68 43 62 50 54 55 64 55 76 40 48 60 62 At the a = 0.05 level of significance, test for any difference in the job satisfaction among the four professions. State the null and alternative hypotheses. O Ho: HL = HPT = Mc = HSA Ha: HL = HPT = HC = PSA O Ho: At least two of the population means are equal. H: At least two of the population means are different. OH :H = = HC= PSA Ha: HL = PPT = HC = PSA O Ho: ML = APT = Kc = HSA H: Not all the population means are equal. O Ho: Not all the population means are equal. Hai PL = HPT = HC = HSA 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. O Do not reject Ho. There is not sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions. O Reject Ho- There is not sufficient ev onclude that the mean job satisfaction rating is not the same for the four professions. Do not reject H. There is include that the mean job satisfaction rating is not the same for the four professions. Reject Hy- There is sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions
