Say method A is superior or the method B is inferior. In this case this statement is termed as an alternative hypothesis. The alternate hypothesis is denoted generally by the symbol Ha or H1.
The null hypothesis and the alternate hypothesis are chosen before the sample is drawn. For making null hypothesis, the important points to remember are:
(a) Null hypothesis represents the hypothesis which a researcher is trying to reject. On the other hand alternate hypothesis is the one which a researcher wants to prove.
(b) If it happens that the hypothesis is rejected when its actually true involves a risk then it is taken as null hypothesis because then the probability of rejecting it when it is true is the level of significance) which is chosen very small.
(c) Always, the null hypothesis should be specific hypothesis.
Hypotheses have been formulated based on the extensive review of available literature. [5] While framing these hypotheses, the researcher has duly considered the inputs from the interviews and discussions with the key personnel during the data collection stage. In the present research, following hypotheses are stated and tested through the investigation in the Data Analysis and Interpretation
