Detailed explanation-1: -Examples of a Null Hypothesis Here is a simple example: A school principal claims that students in her school score an average of seven out of 10 in exams. The null hypothesis is that the population mean is 7.0.
Detailed explanation-2: -The hypotheses are statements made about what we believe to be true with regards to the population mean (represented by the Greek letter mu ( )). The null hypothesis H : = is a statement of “no effect” meaning whatever effect the researcher suspects may be true is, in fact, not present.
