Given the following parameters
The z-score formula is given below
Calculate the z-score value using the above formula by substituting the parameters above
The probability that the score is less than -1.91 can be diagramatically represented as
The probability can calculated as;
[tex]\begin{gathered} Pr(z<-1.91)\Rightarrow Pr(0\le z)-Pr(0
Hence, the probability that a given score is less than -1.91 is 0.0281
