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. lair uk englishNettet6. jan. 2024 · The t-distribution table is a table that shows the critical values of the t distribution.
