Compute Pr(-1.54<Z<1.33)

Question

Suppose that Z is standard normal random variable. Compute Pr(−1.54<Z<1.33).

(If needed, round answers to 3 decimal places)

Answer 1

Pr(z<-1.54) = .059

Pr(z>-1.54) = .50-.059) = .441

Pr(0<z<1.33)= .408

Pr(-1.54 <z<1.33) = .441+.408 = .849

use z tables or a z calculator
