Explanation / Answer
It is given that the regression equation is:
Y=0.065X+87.000
And R^2=0.970
a)Yes, the evidence consistent with the hypothesis that increasing the number of cases per shipment increases transportation cost.
b) The relationship between the variables is very strong and positive as the correlation coefficient is nearly +1.
c) Based on this analysis,the expected additional shipping cost for each extra case per shipment is 87.000.
