p(-1.04

Calculate the probability you entered from the z-table of

p(-1.04 < z < 1.67)

Compound Probability

For probability statements in the form P(a < z < b), this is calculated by finding P(b) - P(a)

P(z < 1.67) - P(z < -1.04)

From our z-table below, we find our two probabilities

p(-1.04 < z < 1.67) = 0.95254 - 0.14917

p(-1.04 < z < 1.67) = 0.80337
