Researcher’s hypothesis would be: Income has a positive impact on job satisfaction.
Part (b)
The table strengthens the researcher’s claim.
27% of the employees belong to lowest income slab and also have the lowest job satisfaction.
33% of the employees belong to highest income slab and also have the highest job satisfaction.
And these two together account for 60% of the employees.
The claim is further confirmed by the fact that a sizable 13% of employees fall into the neutral-middle income slab cell.
The relationship between income and job satisfaction is positive – i.e., as income goes up, job satisfaction also gets elevated.
