If the sample is ‘large’ enough with both npnp and nqnq 10 or more, then ˆp^p will be approximately normal. ˆp ˙ ∼ N(p, √p(1 − p) n) This is the basis for our formula for the confidence interval for pp in chapter 16 and will also be used when we study hypothesis testing for a ... 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. orange raspberry pi accessories cheap display https://collectivetwo.com
