Find the P-value for the following values of the test statistic t, sample size n, and alternate hypothesis H1. If you use Table A.3, you may specify that P is between two values.

a. t = −1.584, n = 19, H1: μ ≠ μ0

b. t = −2.473, n = 41, H1: μ

c. t = 1.491, n = 30, H1: μ ≠ μ0

d. t = 3.635, n = 4, H1: μ > μ0
