## 9.2$$P$$-values

In a two-tailed $$t$$-test where $$n=49$$, what is the approximate $$P$$-value for the test (Hint: Use the 68–95–99.7 rule) if:

1. $$t=-2.14$$.
2. $$t=1.90$$.
3. $$t=3.15$$.
4. $$t=-1.20$$.
5. $$t=-1.59$$.
6. $$t=6.71$$.

How would your answers change if these $$t$$-scores came from a one-tailed test?
