need asap show simplest or even answer only. will give good feedback as usual

Calculate and interpret the coefficient of determination R OR? = 0.884 88.4% of the observed variance of strength about their mean is attributable to the linear relationship between strength and age. O R2 = 0.940 94.0% of the observed variance of strength about their mean is attributable to the linear relationship between strength and age. O R2 = 0.877 87.7% of the observed variance of strength about their mean is attributable to the linear relationship between strength and age. O R2 = 0.884 (100 - 88.4)% of the observed variance of strength about their mean is attributable to the linear relationship between strength and age. O R2 - 0.940 (100 - 94.0)% of the observed variance of strength about their mean is attributable to the linear relationship between strength and age.A rocket motor is manufactured by bonding together two types of propellants, an igniter and a sustainer. The shear strength of the bond is thought to be a linear function of the age of the propellant when the motor is cast. Twenty observations are shown in the following table.
