Similarly, about 95% of the distribution would be between 50 - 2 x 10 = 30 and 50 + 2 x 10 = 70. Figure 3.3.3: Percentages of the normal distribution.
WebNov 5, 2024 · The data follows a normal distribution with a mean score ( M) of 1150 and a standard deviation ( SD) of 150. 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.
