What is testing of hypothesis?
Suppose there is a data at hand and there is a hypothesis to be tested. Testing of hypothesis determines whether the given hypothesis can be supported with the data at hand.
A student believes that the average grade on the final examination in statistics is at least 85.
The null hypothesis is [tex]\mu \geq 85[/tex]
The alternative hypothesis is [tex]\mu < 85[/tex]
So, the correct set of hypotheses is
[tex]H_0 : \mu \geq 85[/tex]
[tex]H_a : \mu < 85[/tex]
