Find the z score corresponding to x 19
WebExplanation: A z-score of +1.50 indicates that the score of X = 15 is 1.5 standard deviations above the mean. 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. WebIn 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.

WebYou shouldn't be getting the standard deviation or the mean from a Z-table. The Z-table assumes a mean of 0 and a standard deviation of 1 (hence why we calculate a z-score before going to the table). The table has two uses: 1. Calculate a z-score and find the probability under the curve. 2. Look up a probability and find the z-quantile. 2 comments WebApr 26, 2024 · There are three ways to find the z-score that corresponds to a given area under a normal distribution curve 1.
