Solution

1. Any test for statistical inference is known as statistical hypothesis test. The test assumes two hypotheses, one is alternative and other is null hypothesis. The data is then tested to obtain the results with respect to the set alternative hypothesis. Within a given domain of values one of the two hypotheses is selected. The test is therefore a method to compare two statistical data sets or a data set obtained by sampling is compared against a synthetic data set from an idealized model.
