What is the probability of randomly selecting a 2-score greater than z = 0.75 from a normal distribution? P = 0.4878 p = 0.2734 p' = 0.7734 p = 0.2266

The proportion of observations from a standard Normal distribution with values larger than $-0.75$ is $\begin{array}{ll}{\text { (a) } 0.2266 .} & {\text { (c) } 0.7734} \\ {\text { (b) } 0.7422} & {\text { (d) } 0.8023}\end{array}$
