WebNov 5, 2024 · You want to find the probability that SAT scores in your sample exceed 1380. To standardize your data, you first find the z score for 1380. The z score tells you how many standard deviations away 1380 is from the mean. Step 1: Subtract the mean from the x value. x = 1380. M = 1150. x – M = 1380 − 1150 = 230.

With smaller samples, the sample variance will equal the population variance on average, but the discrepancies will be larger. If symmetrical as variances, they will be asymmetrical as SD. starting executable failed
