A rocket motor is manufactured by bonding together two types of propellants, an igniter and a sustainer. A random sample of 26 specimens is used to investigate the relationship between the shear strength of the bond in psi and the age of the propellant in weeks. Below is the R output for the estimated linear regression. Coefficients: (Intercept) Shearstrength Estimate Std. Error t value Pr(>1t|) 2760.3 57.68 47.85 < 2e-16 -37.4 3.21 -11.65 2.3e-11 Q5.1 1 Point The population regression equation is My = Bo + B12 where y is the shear strength in psi and 3 is the age of the propellant in weeks. Determine the estimate for Bo. O 2760.3 -37.4 57.68 O 3.21 Q5.2 1 Point Determine the estimate for B1. O 2760.3 -37.4 57.68 O 3.21 Q5.3 1 Point Interpret the slope coefficient. O When the age of the propellant is O weeks, the predicted shear strength is 2760.3 psi. When the age of the propellant is O weeks, the predicted shear strength is -37.4 psi. For every one week increase in propellant age, shear strength is predicted to increase by 37.4 psi. O For every one week increase in propellant age, shear strength is predicted to decrease by 37.4 psi. Q5.4 3 Points Predict the shear strength of the bond for a propellant that is 17 weeks old.
