Question

A) If Z is standard normal, then P(Z < 0.5) is

Answer 1

We have given the Z is standard normal and we are asked to find P(Z < 0.5)

We use Z table beacuse Z table always give you the left side area

We write the 0.5 as 0.50

We look for row headed 0.5 and column headed .00

We get the area 0.6915 from the table

so P (Z < 0.5 ) = 0.6915

Final answer :-

P(Z < 0.5 ) = 0.6915

I hope this will help you :)
