    The idea of the null hypothesis is that it is null (negative) i.e. it is always that what ever you are testing for has no effect. So for example, a particular drug kills a person and is given to 500 people. A week later 450 of those people are dead state a null hypothesis and an alternate hypothesis.
    Null hyp: The drug does not kill the people.
    Alternate: The drug does kill the people.

    You then carry out the statistical test to either prove your alternate hyp correct of false.

    Sorry the example is so morbid but i doubt you will forget it!!!
