Question

### T-Test and P-Value Calculation

You are performing a right-tailed t-test with the following parameters:
- **Test statistic (t)**: 2.6
- **Sample size (n)**: 21

**Objective**: Find the p-value to four decimal places.

To find the p-value, you would typically use the t-distribution table or statistical software. You need the degrees of freedom, which is sample size minus one (n-1). In this case, the degrees of freedom is 20. Use this information to look up the p-value for a right-tailed t-test with the given t-statistic.
