Find the z score corresponding to x 25

WebNov 5, 2024 · x – M = 1380 − 1150 = 230. Step 2: Divide the difference by the standard deviation. SD = 150. z = 230 ÷ 150 = 1.53. The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from … WebSolution:- Give data, Mean= = 30 Standard deviations = =5 Z score can be calculated by following formula Z = ( - )÷ Now, a) given =25 Hence, Z = (25-30)÷5 Z = -1 Hence, que a) …

WebSo if the standard deviation of the data set is 1.69, a z-score of 1 would mean that the data point is 1.69 units above the mean. In Sal's example, the z-score of the data point is -0.59, meaning the point is approximately 0.59 standard deviations, or 1 unit, below the mean, which we can easily see since the data point is 2 and the mean is 3. WebThen, based on the definition formula of a z-score, we need to solve for (\(X\)) in order to find the corresponding raw score, and we apply the following formula obtained from solving the equation. \[X = \mu + Z \times \sigma\] Raw Score Example brakisto https://artattheplaza.net
