Find the following probability for a standard normal random variable, P(Z < 1.73). 1).9582 O2).0418 O3).1354 4) 9107
Let the random variable Z follow a standard normal distribution. Find P(-2.35 < Z< -0.65). Your Answer:
(1 point) Find the following probabilities for the standard normal random variable z. (a) P(-0.81 <<0.42) (b) P(-1.14 <z < 0.5) (c) P(Z < 0.69) a (d) P(Z > -0.6)
(1 point) Find the value of the standard normal random variable z, called Zo such that: (a) P(Z <zo) = 0.8319 20 (b) PC-Zo <z<zo) = 0.5508 20 = (c) P(-20 <2<zo) = 0.748 zo = (d) P(z > Zo) = 0.2823 20 = (e) P(-20 <z<0) = 0.0283 Zo = (1) P(-1.5 <2<zo) = 0.7108 zo Note: You can earn partial credit on this problem.
