a. The equation for a line of regression, ŷ = a + bx, is: bırth rate = a + bgnp where gnp is the explanatory variable for the birth rate, the response variable. Using the summary statistics given above, show how to calculate both the slope coefficient and the intercept (do not round any numbers until the end). Show all working out. The estimates of a and b (correct to 4 d.p.) from the above dataset are: a = 47.1821 b= -0.0064
