Let us say that average marks in mathematics of class 8th students of ABC School is What can be concluded from this experiment? Here are the conclusions: There is no difference at all. The result is due to random chance only i. How should we decide which explanation is correct?

Lecture 8: Hypothesis testing 2nd of December Collecting a dataset Once we have set up our null and alternative hypothesis we can collect a sample of data.
Test statistics and critical regions We can also compare the test statistic under the null hypothesis z= x ˙= p n. Can you explain the purpose of null hypothesis testing and provide examples of null hypothesis that may be tested with the data set. (data set is anorexia)?
