An insurance manager believes that the number of new policies written annually by his agents is related to the number of years of selling experience that these agents have. A random sample of 12 agents revealed the data in the table below: Number of years of experience Number of new policies written annually 2 17 5 22 7 34 6 37 12 50 9 41 5 13 20 48 13 39 4 20 10 35 20 63 2.1 determine the dependent and the independent variable 2.2 using appropriate computational formulae find the least-square regression line. 2.3 Interpret the y- intercepts of regression equation in question 2.2 above
