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. WebHow to find z critical value? Example: Find the z critical value if the significance level is 0.02. Solution: Step 1: Divide the significance level α by 2 α/2 = 0.02/2 α/2 = 0.01. Step 2: Subtract α/2 from 1. 1 - α/2 = 1 – 0.01 1 - α/2 = 0.99. Step 3: Search the value 0.99 in the z table given below. Add the values of intersecting row ...
WebApr 14, 2024 · The basic process for doing so is as follows: Step 1: Calculate the test statistic using raw data. Step 2: Compare the test statistic to the t critical value (tα/2). Step 3: Reject or fail to reject the null hypothesis of the test. If the absolute value of the t test statistic is greater than the t critical value, then we can reject the null ...
