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 relatethe 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)x, = dynamic hand grip endurance (seconds)x, = trunk extension ratio (N/kg)Suppose that the model equation is the following and that o = 5.y = 31 + 0.91x, + 0.07x2 - 4.40x3 + e(a) What is the population regression function?y =(b) What are the values of the population regression coefficients?B1 =B2 =B3 =(c) Interpret the value of B,.When.Select::.v are fixed, the mean -Select---in rating of acceptable load associated with a ---Select--- v increase in--Select--is 0.91 kg.(d) Interpret the value of B3.When ---Select---v are fixed, the mean ---Select--- v in rating of acceptable load associated with a---Select--- v increase in---Select---v is 4.40 kg.

The Conde Nast Traveler Gold List for 2012 provided rating for the top 20 small cruise ships. The data from annual Readers’ Choice Survey are the overall scores(Y) each ship received based on several criteria, including Itineraries/Schedule (X1), Shore Excursions(X2), and Food/Dinning(X3). The estimated regression equation to predict the overall scores is Y= 35.6184+0.1105 X1+0.2445 X2+0.2474 X3. Part of the regression results is shown below.
