What are the steps in the critical value approach?
Here, we are going to describe the four important steps involved in the critical value approach to conduct the test of the hypothesis is: State the hypothesis as a null hypothesis or as an alternate hypothesis. By using the sample data set, assume the null hypothesis to be true, and calculate the test statistic value.
When is the null hypothesis not rejected by the critical value?
If the test statistic is more extreme than the critical value, then the null hypothesis is rejected in favor of the alternative hypothesis. If the test statistic is not as extreme as the critical value, then the null hypothesis is not rejected.
How is the critical value approach used in hypothesis testing?
The critical value approach involves determining "likely" or "unlikely" by determining whether or not the observed test statistic is more extreme than would be expected if the null hypothesis were true. That is, it entails comparing the observed test statistic to some cutoff value, called the " critical value .".
What's the difference between test statistic and critical value?
Whereas test statistic values less than the lower critical value and more than the upper critical value indicate rejection of the null hypothesis for the test. We can summarize this interpretation as follows:
