Exercises pertain to P-values for a one-mean t-test. For each exercise, do the following tasks.

a.Use Table IV in Appendix A to estimate the P-value.
b.Based on your estimate in part (a), state at which significance levels the null hypothesis can be rejected, at which significance levels it cannot be rejected, and at which significance levels it is not possible to decide.

Right-tailed test, n = 20, and t = 2.235
