All of the Following Are Examples of Joint Hypotheses on Multiple

Short Answer

All of the following are examples of joint hypotheses on multiple regression coefficients, with the exception of a. $H _ { 0 } : \beta _ { 1 } + \beta _ { 2 } = 1$ .
b. $H _ { 0 } : \frac { \beta _ { 3 } } { \beta _ { 2 } } = \beta _ { 1 }$ and $\beta _ { 4 } = 0$ .
c. $H _ { 0 } : \beta _ { 2 } = 0$ and $\beta _ { 3 } = 0$ .
d. $H _ { 0 } : \beta _ { 1 } = - \beta _ { 2 }$ and $\beta _ { 1 } + \beta _ { 2 } = 1$ .
