Calculate a Z score when X = 20, μ = 17, and σ = 3.4. Using a standard normal probabilities table, interpret the results for the Z score.

A

The right-tailed p-value of 0.188 indicates that the value of 20 or greater would occur in 18,8% of cases. The left-tailed p-value of 0.811 indicates that the value of 20 or lower would occur in 81.11% of cases.

z = (x-μ)/σ = (20-17)/3.4 = 0.882
