It is claims that the relationship between the x and y can be modelled through a regression model as follows: j =a+bx where a and ò are the estimated values for a and ß (refer to Appendix). Determine the equation of the regression line to predict the y value from the x value. (ii) If the y value is 60, what is the value of x?
