- If Z is a standard normal random variable, and a normal table tells you that P[Z<=1.5]=.9331 and that P[Z<=.2]=.5793, then find P[.2<=Z<=1.5].Suppose the random variable Z follows a standard normal distribution (the tabled curve). Find the chance Z is greater than 1.26. P(Z > 1.26) = Use 4 decimal places.Please see below.
