Web5 de nov. de 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. WebSuccess/Failure Condition: If we expect at least 10 successes (np ≥ 10) and 10 failures (nq ≥ 10), then the binomial distribution can be considered approximately Normal.
