Test Statistic

The next  step is compute an appropriate  test statistic which  is based on an appropriate probability distribution. It  is used to test whether the null  hypothesis set up  should be  accepted or rejected. For  this purpose we use Z distribution  under normal  curve for  large sample  where the  sample size is  equal  to or larger than 30 (n ≥ 30) and  the distribution for small  sample  where  the sample  size  n less  than 30 ( n< 30).
