**Hypothesis
Testing**

One of the important
areas of statistical analysis is testing of hypothesis. Often, in real life
situations we require to take decisions about the population on the basis of
sample information. Hypothesis testing is also referred to as “Statistical
Decision Making”. It employs statistical techniques to arrive at decisions in
certain situations where there is an element of uncertainty on the basis of
sample, whose size is fixed in advance. So statistics helps us in arriving at
the criterion for such decision is known as Testing of hypothesis which was
initiated by J. Neyman and E.S. Pearson.

For Example: We may like
to decide on the basis of sample data whether a new vaccine is effective in
curing cold, whether a new training methodology is better than the existing
one, whether the new fertilizer is more productive than the earlier one and so
on.
