Multiple regression analysis was used to study the relationship between a dependent variable, y, and three independent variables x₁, x₂ and, x₃. The following is a partial result of the regression analysis involving 20 observations. a.Compute the coefficient of determination. b.Perform a t test and determine whether or not $\beta$₁ is significantly different from zero ($\alpha$ = 0.05). c.Perform a t test and determine whether or not $\beta$₂ is significantly different from zero ($\alpha$ = 0.05). d.Perform a t test and determine whether or not $\beta$₃ is significantly different from zero ($\alpha$ = 0.05). e.At $\alpha$ = 0.05, perform an F test and determine whether or not the regression model is significant.
