Example 2: If the raw score is given as 250, the mean is 150 and the standard deviation is 86 then find the value using the z table. Solution: The formula for the z score is given as. z = x−μ σ x − μ σ. x = 250, μ μ = 150 and σ σ = 86. z = 1.16. Using the positive z table the value is 0.8770. Answer: 0.8770.
