A number of investigations have focused on the problem of assessing weights that can be lifted in a safe manner. A particular article proposed using a regression model to relate the following dependent variable (y) to k = 3 independent (predictor) variables. y = individual's rating of acceptable weight (kg) x, = extent of left lateral bending (cm) X2 = dynamic hand grip endurance (seconds) x3 = trunk extension ratio (N/kg) Suppose that the model equation is the following and that o = 5. y = 31 + 0.91x, + 0.07x, - 4.40x3 + e (a) What is the population regression function? y = (b) What are the values of the population regression coefficients? B = B2 = B3 = (c) Interpret the value of B,. When.Salect::... v are fixed, the mean ---Select--- v in rating of acceptable load associated with a -Select-- increase in --Select--- v is 0.91 kg. ........
