### HYPOTHESIS-MEANING:

HYPOTHESIS-MEANING A hypothesis is a tentative assumption relating to certain phenomenon, which the researcher wants to verify when required. it is an unproven statement or proposition about a factor or phenomenon that is of interest to the researcher. An important role of a hypothesis is to suggest variables to be included in the research design.

### Null Hypothesis ,(H0 ):

Null Hypothesis ,( H 0 ) This hypothesis states that there is no difference between the parameter and the statistic that is being computed. Eg If we are to compare method A with method B about its superiority and if we proceed on the assumption that both methods are equally good,then this assumption is termed as the null hypothesis.

### ALTERNATIVE HYPOTHESIS(H1):

ALTERNATIVE HYPOTHESIS (H 1) Is the opposite of null hypothesis. Eg - we may think that the method A is superior or the method B is inferior, we are then starting what is termed as alternative hypothesis.

### EXAMPLE :
