Need help ASAP!!!

I am trying to figure out if income should be used to predict sales based on a small sample.

My r2 = 48.75% So I know there is not a strong linear relationship, but a weak correlation.

But my f stat is greater than f critical value which means disposable income is significantly related to annual sales.

Also 0 is my confidence interval and t stat > than t critical value which all indicate a linear association between sales and income.

Also sales is measured by millionas and income is measured by($000)
Simple linear regression equation = p hat = -1.94 +0.19(income)

IS IT OK TO SAY THAT AVERAGE INCOME SHOULD NOT BE USED TO PREDICT SALES?
