answer the questions

iii) Test whether there is a relationship between number of building permits issued and interest ret and hence whether interest rate should be included in the regression model to explain number of building permits issued. iv) It is believed that the higher the interest rate, the few the number of building permits issued. Is the slope coefficient consistent with this hypothesis? Briefly justify your answer. v) Use the information from the ANOVA table to test if R-=0. Briefly explain whether this is the same as testing the coefficient on interest rate equals to zero or not
