In Statistics and mathematics, the degrees of freedom in a sample are used to correct: A. possible bias between the alternative and null hypotheses.

### What is a null hypothesis?

A null hypothesis ( ) can be defined as the opposite of an alternate hypothesis ( ), and it asserts that two (2) possibilities are the same.

In In Statistics and mathematics, the test statistics of a given sample is calculated with this formula: Where:

• x is the sample mean.
• u is the mean.
• is the standard deviation.
• n is the sample size.

Also, the degrees of freedom in a sample are used to correct a possible bias that exists between the alternative and null hypotheses.
