WebIf you have the z score of something then you know how many std dev of 1 it is from a mean of 0 with a std dev of 1. If you know the std dev then I think you can just multiply to figure out what the actual value of said z-score then using the std dev you should be able to locate the mean.

WebRow labels of Table A.1 give possible z-scores up to one decimal place. The column labels give the second decimal place of the z-score. The cumulative probability for a value equals the cumulative probability for that value's z-score. Here, probability speed less than or equal 73 mph = probability z-score less than or equal 1.60. WebIf you want to calculate the probability for values falling between ranges of standard scores, calculate the percentile for each z-score and then subtract them. For example, the probability of a z-score between 0.40 … WebMar 24, 2024 · Use the following format to find a z-score: z = X - μ / σ.
