Respuesta :
As per question, ‘Z’ is a standard normal random variable. And the value of ‘z’ is [tex]0.9878.[/tex]
According to the question, the area to left of ‘z’ and the equation can be written as:
[tex]P(Z > z) =0.01222[/tex]
Therefore,[tex]P(Z < z) =1-0.01222=0.9878[/tex]
Now the desired z-score corresponding to z-table graph = [tex]2.25[/tex]
