For example, The workers who do night shifts will have are disturbed sleeping patterns than those who do morning shifts.

There may be instances that your dissertation will involve statistical Hypothesis testing for which you should write a null Hypothesis. According to the null Hypothesis, both the variables have no relationship between them. The null Hypothesis is usually denoted by H0.

For example, Workers who do night shifts do not have disturbed sleeping patterns.

The opposite of the null Hypothesis is called the alternative Hypothesis which is often denotd by H1.  It suggests that there is a relationship between the variables.
