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) x₁ = extent of left lateral bending (cm) X₂ - dynamic hand grip endurance (sec) X-trunk extension ratio (N/kg) Suppose that the model equation is the following and that a = 5. y = 31 +0.89x₂ + 0.07x₂-4.40x₂ + e LAUSE SALT (a) What is the mean rating of acceptable weight (in kg) when extent of left lateral bending is 35 cm, dynamic hand grip endurance is 210 sec, and trunk extension ratio is 12 N/kg? kg (b) If repeated observations on rating are made on different individuals, all of whom have the values of x₁, x₂, and x₂ specified in part (a), in the long run approximately what percentage of ratings will be between 14.05 kg and 34.05 kg? (Round your answer four decimal places.)
