Final answer:

The degrees of freedom in a t-test are determined by the sample size.

Step-by-step explanation:

In the t-test, the degrees of freedom are a function of: c) The sample size.

The number of degrees of freedom in a t-test is calculated as df = n - 1, where n is the sample size. The degrees of freedom determine the critical values and the shape of the t-distribution. It is important for calculating the t-statistic and determining the p-value.
