Find x from z score
WebJan 22, 2024 · Explanation: Relation between z -scores and x -scores is given by z = x − μ σ, where μ is the mean and σ is standard deviation. As z = 1.50, μ = 7 and σ = 10, we have 1.5 = x −7 10 i.e. x − 7 = 1.5 × 10 = 15 and x = 22 Answer link WebFinite Math. Use the Table to Find the z-Score 0.99. 0.99 0.99.
