Find a value of z such that 43.7 of the distribution lies between it and the mean. (Hint: There are two possible answers.)

Question 2

Find the z-score for the first quartile of the standard normal distribution.

Answer to Question 1

Since P(0 < z < 1.53) = 0.437 = P(-1.53 < z < 0), then z = 1.53.

Answer to Question 2

Since P(z < -0.67) = 0.2486 0.25, then the z-score for the first quartile of the standard normal distribution is -0.67.
