WebStep 1: Identify the values and write them down. x = 10 μ = 35 σ = 12 Step 2: Place the values in z-score equation. Z = (x – μ) / σ Z = (10 – 35) / 12 Z = -25/12 Z = -2.083 The zscore of -2.083 means that the raw score is below the mean. We can interpret as: Z-score is -2.083 standard deviations below the mean. WebTo find z, use the z table or technology. In the z table, find the area closest to 0.6491 then locate the z-score by joining the left-most column and the top row reference values. z = 0.38. (c) Given: area to the right of z is 0.1639. First, find the area to the left of z by subtracting this area from 1.
