The p-value for a one-sided left-tail test a. is given by $\operatorname { Pr } \left( Z t ^ { a c t } \right) = \phi \left( t ^ { a c t } \right)$. b. is given by $\operatorname { Pr } \left( Z

Question

The p-value for a one-sided left-tail test a. is given by $\operatorname { Pr } \left( Z > t ^ { a c t } \right) = \phi \left( t ^ { a c t } \right)$.
b. is given by $\operatorname { Pr } \left( Z < t ^ { a c t } \right) = \phi \left( t ^ { a c t } \right)$.
c. is given by $\operatorname { Pr } \left( Z < t ^ { a c t } \right) < 1.645$.
d. cannot be calculated, since probabilities must always be positive.
