A one$-$way ANOVA was carried out to determine whether management styles $($Authoritarian$,$ Laissez faire and Participative$)$ differ among organizations and may potentially affect employee$$s job satisfaction $($measured on a $10-$point scale where $10=$high$).$ The null hypothesis to be tested is $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_.$

Group of answer choices

management styles do not affect employee job satisfaction ratings, hence the mean satisfaction ratings are equal across the different employees

mean employee job satisfaction ratings are not all equal across companies with different management styles, hence the satisfaction ratings are not equal across employees

None of the answer choices

management styles are different across the different organization hence the mean satisfaction ratings are not equal across the different employees
