Find a value of the standard normal random variable z
Find a value of the standard normal random variable z, call it z0, such that the following probabilities are satisfied.
ÿ1. P(z<=z0) = 0.7405
ÿ2. P(-z0<=z<=z0) = 0.8712
ÿ3. P(-z0<=z<=0) = 0.4741
ÿ4. P(-1<z<z0) = 0.5886
ÿ
ÿ1. z0 = (Round to two decimal places as needed.)
ÿ2. z0 = (Round to two decimal places as needed.)
ÿ3. z0 = (Round to two decimal places as needed.)
ÿ4. z0 = (Round to two decimal places as needed.)
