Explanation / Answer
1)
Null hypothesis in general means 'no change' or 'no difference'. It is the hypothesis wherein we try to prove that there is no difference between the specified populations. Alternative hypothesis on the other hand is the opposite of null hypothesis. It tries to prove that there is a difference between the specified populations.
2)
Type 1 error occurs when we reject a true null hypothesis. Type 2 error on the other hand occurs when we incorrectly retain a false null hypothesis.
3)
The steps in hypothesis testing methodology are as follows: -
a) State the null and alternate hypothesis.
b) Choose the level of significance.
c) Determine the appropriate test statistic.
d) Determine the critical values and critical region.
e) Compute the test statistic.
f) Make a statistical conclusion and provide managerial decision.
