"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 the mean of your distribution. Next, we can find the probability of this score using a z table. " - Cumulative function of normal distribution
