(4) Find the p-value for testing Ho: ßj = o versus Ha: ßj * 0 on the output. Using the p-value, determine whether we can reject Ho by setting a equal to 10, .05, .01, and .001. What do you conclude about the significance of the independent variables in the model? (Round your answers to p-value at ß2 = 0 and B3 = 0 to 4 decimal places. Round other answers to 3 decimal places.) HO: B1 = 0 is HO: B2 = 0 is ; Reject H0 at a = ; Reject HO at a = HO: B3 = 0 is ; Reject HO at a = (5) Calculate the 95 percent confidence interval for ß1. (Round your answers to 3 decimal places. Negative values should be indicated by a minus sign.) 95% C.I. B0 B1 B2 B3
