Introduction

Any assumption about the parameter or probability function is called Hypothesis test. There is always some contention about the values of a parameter . When parametric values are unknown. we estimate them through samples values. If the sample value is exactly the same as per our contention there is no high in accepting it. And it if it is far from our contention there is no reason to accept it.
