## Answer to relevant Questions

Find the value of t for the difference between two means based on an assumption of normality and this information about two samples: Suppose the calculated t had been 1.80 in Example 10. 10 (pp. 500–501). Using df = 9 or using df = 20 results in different answers. Explain how the word conservative (p. 496) applies here.
