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.

State the null and alternative hypotheses. O Ho: At least two of the population means are equal. H : At least two of the population means are different. O HO: ML = HPT " HC = HSA He: HL MPT * PC # HSA O HO: HL = MPT " HC = HSA H.: Not all the population means are equal. O HO: HL* HPT * HC* HSA Hal KL = MPT " HC " HSA O Ho: Not all the population means are equal. He: HL " 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. Reject Ho. There is sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions. 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. Do not reject Ho. There is sufficient evidence to conclude that the mean job satisfaction rating is not the same for the four professions. Reject He. There is not sufficient evidence to conclude that the mean jo
