On an exam with u = 52, you have a score of X = 56.
WebHow do we find the Z score? First, convert the variance (σ 2) to standard deviation (σ) by taking its square root: σ = √90000 = 300. Then the solution is simply: z = (1600 - 1000) / 300 = 600 / 300 = 2 This tells us that the … WebSince the z-score is the number of standard deviations above the mean, z = (x - mu)/sigma. Solving for the data value, x, gives the formula x = z*sigma + mu. So the data value equals the z-score times the standard deviation, plus the mean. Have a blessed, wonderful …

Answer 2: -1.00. Explanation: To find the z-score corresponding to X = 80, we use the formula z = (X - µ) / σ, where X is the score, µ is the mean, and σ is the standard deviation.
WebOct 9, 2024 · A z-score of 1.7 was found from an observation coming from a normal distribution with mean 14 and standard deviation 3. Find the raw score. Solution Plugging these into Equation 1, we have 1.7 = x − 14 3 To solve this we just multiply both sides by the denominator 3, ( 1.7) ( 3) = x − 14 5.1 = x − 14 x = 19.1 The z-score and Area
