a) In the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. If the p-value is less than 0.05, we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist.
So, if p < 0.05 then variable is significant
From table we can see that only job growth and industry are significant as they have p < 0.05
b) A option
Interactive model of job growth * industry is good
