3)using excel and Given that z is a standard normal random variable, what is the value for z0 if: a. P(z > z0) = 0.12 b. P(z < z0) = 0.2 c. P(z > z0) = 0.25 d. P(z < z0) = 0.3
If the random variable z is the standard normal score and a >0 is it true that p ( z >a ) = p ( z < a ) ? Why pi r Why or What not? yes because normal distribution means is 0 and variance is 1. What is the property does the distribution have?
Given that z is a standard normal random variable, find z for each situation (to 2 decimals) a. The area to the right of z is 0.03. b. The area to the right of z is 0.045 c. The area to the right of z is 0.05 d. The area to the right of z is 0.1
