Let me know in the comments if you have any questions on $Z$-test calculator for proportion with examples and your thought on this article. To learn more about other hypothesis testing problems, hypothesis testing calculators and step by step procedure, please refer to the following tutorials:
ONE TAILED HYPOTHESIS TEST CALCULATOR HOW TO
You also learned about the step by step procedure to apply $Z$-test for testing single proportion and how to use Z-test calculator for testing population proportion to get p-value, z-critical value.

In this tutorial, you learned the about how to solve numerical examples on $Z$-test for testing single proportion. There is no sufficient evidence to say that the percentage of men who use exercise to reduce stress is not $14$%. If the consumer group found that 55 of the claims were settled within 30 days, do they have sufficient reason to support their contention that fewer than 90% of the claims are settled within 30 days? Use 5% level of significance. A consumer group selected a random sample of 75 of the company's claims to test this statement.

Step 6 - Click on "Calculate" button to get the result Z-test for testing proportion Example 1Īn insurance company states that 90% of its claims are settled within 30 days. Step 5 - Select the alternative hypothesis (left-tailed / right-tailed / two-tailed) Step 4 - Enter the level of significance $\alpha$ Step 3 - Enter the observed number of successes $X$ Step 1 - Enter the population proportion $p$ under $H_0$. Two tailed Calculate Results Sample Proportion : Standard Error of $p$: Test Statistics Z: Z-critical value: p-value: How to use $z$-test calculator for testing single proportion? If the hypothesis says that the mean of one group is larger or smaller than the mean of the other group, this must also be seen in the result. Now it depends on whether the data tend 'in the direction' of the hypothesis or not.
