WebOct 23, 2024 · The data follows a normal distribution with a mean score (M) of 1150 and a standard deviation (SD) of 150. Following the empirical rule: Around 68% of scores are between 1,000 and 1,300, 1 standard deviation above and below the mean. Around 95% of scores are between 850 and 1,450, 2 standard deviations above and below the mean. 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. instinct education reviews https://australiablastertactical.com
