# Question

Estimate the p-value as a range using Appendix D (not Excel):

a. t = 1.457, d.f. = 14, right-tailed test

b. t = 2.601, d.f. = 8, two-tailed test

c. t = 21.847, d.f. = 22, left-tailed test

a. t = 1.457, d.f. = 14, right-tailed test

b. t = 2.601, d.f. = 8, two-tailed test

c. t = 21.847, d.f. = 22, left-tailed test
