      2 Sample t-Test: Degrees of Freedom: Since we don’t know the standard deviations we use the t-distribution for our test statistic. But we have a problem with calculating the degrees of freedom! We have two options: Let our calculator handle the complex calculations and tell us what the degrees of freedom are
