As no data are given, I am assuming you are looking for explanation of null and alternative hypothesis.

Null Hypothesis - In a test, the statement being tested is called the Null Hypothesis. For example, if you are testing the mean weight is 187 or not, then mue = 187 is null hypothesis.

Alternative hypothesis is the is the statement we suspect is true . For example, in the situation above, that alternative hypothesis would be mean weight mud not equal to 187.
