what is The test statistic rounded to two decimal places ?

The test statistic, rounded to two decimal places, is \( t = 0.21 \).

Would you like further clarification on this or any related questions? Here are some related questions for practice:

1. How do you interpret the result of the test statistic?
2. What are the degrees of freedom for this test?
3. How do you calculate the critical value for a one-tailed t-test with 0.05 significance level?
4. How does the assumption of equal standard deviations affect the test?
5. What would happen if the standard deviations were significantly different?

**Tip:** Always check the assumptions (like equal variances) before applying a t-test to ensure the method is appropriate for your data.
