Researcher a Hypothesizes That the Prestige of Someone's Occupation Is

Researcher A hypothesizes that the prestige of someone's occupation is determined by income: the higher the income, the more prestige. Researcher B hypothesizes that, while income may play a role, education also plays a role: the higher the education, the more the prestige.
Here are results from a set of models using GSS2008 data (the dependent variable - occupational prestige score - is measured from a low of 17 to a high of 86). Address the researchers' hypotheses by interpreting this output.
