a.(4 points) Given a standard normal random variable Z~N(0,1). Do the following:

(i) Compute P(-1.5 < Z < -0.6). (Show the area in the standard normal curve graph.)

(ii) Compute P(-0.6 < Z < 1.24). (Show the area in the standard normal curve graph.)

(iii) Find a value z such that P( Z>z) = 0.1003. (Show the area in the standard normal curve graph.)

(iv) Find z such that by using the normal table at the end of this exam paper.
