How to test the null hypothesis of a mutual fund?
The null hypothesis is that the mean return is 8% for the mutual fund. We take a random sample of annual returns of the mutual fund for, say, five years (sample) and calculate the sample mean. We then compare the (calculated) sample mean to the (claimed) population mean (8%) to test the null hypothesis.

When is a null hypothesis rejected by Fisher?
Fisher’s significance testing approach states that a null hypothesis is rejected if the measured data is significantly unlikely to have occurred (the null hypothesis is false). Therefore, the null hypothesis is rejected and replaced with an alternative hypothesis.
What is the significance of the null hypothesis?
The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.
