Determine z for the following values of α:
Webz = (6873 – 6800) / [400/sqrt (100)] z = 73 / [400/10] z = 73/ [40] z = 1.825. So, the z-test result, also called the test statistic is 1.825. Step 4: Using the z-table, determine the rejection regions for you z-test. To do this, you must first select an alpha value. The alpha value is the percentage chance that you will reject the null ...

If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's …
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. WebNov 6, 2024 · The level of significance which is selected in Step 1 (e.g., α =0.05) dictates the critical value. For example, in an upper tailed Z test, if α =0.05 then the critical value is Z=1.645. The following figures illustrate …
