Question

Given that z is a standard normal random variable, what is the value of z if the area to the right of z is .9370? a. .8264 b. – 1.53 c. 1.50 d. 1.96

Answer 1

z₁(s) = - 1.53

Explanation:

a) Value of z or z₁(s) area to the right is .9370

1 - 0.9370 = 0.063

Then if area to the left is 0.063 z₁(s) = - 1.53
