At the a = 0.05 level of signicance, test for any difference in the job satisfaction among the four professions. A hypothesis test is to be conducted to determine if there Is any difference in the job satisfaction among the four professions. The null hypothesis, \"0- is a statement that is assumed to be true. The alternative hypothesis, Ha, is what the test is attempting to establish. If there is no effect of profession, then the population means of job satisfaction will not differ. The alternative hypothesis for testing the equality of population means will always have the same form, that they are not all equal. Note that this does not necessarily mean that each population mean is different, just that they are not all the same value. Therefore, we have the following hypotheses. 0H0: HL=FPT=FC=F5A H : Not all the population means are equal. 0 Ho: At least two of the population means are equal. H : At least mo of the population means are different
