(a) two-tailed test, level of Significance = .01, df = 28 (b) one-tailed test, lower tail critical, level of significance = .05, df = 16 (c) one-tailed test, upper tail critical, level of significance = .01, df = 8
- Find the critical t-values for the following hypothesis tests
(a) two-tailed test, level of Significance = .01, df = 28
(b) one-tailed test, lower tail critical, level of significance = .05, df = 16
(c) one-tailed test, upper tail critical, level of significance = .01, df = 8 (d) two-tailed test, level of Significance = .05, df = 15
(e) two-tailed test; level of significance .01, n1 = 14 n2 = 12
(f) one-tailed test, lower tail critical; level of significance .05, n1 = 14, n2 = 13
(g) one-tailed test, upper tail critical; level of significance .01, n1 = n2 = 25
(h) two-tailed test; level of significance .05, n1 = 9, n2 = 11
Find the approximate p-value for each of the following test results:
(a) one-tailed test, lower tail critical: df = 22, t= -2.92
(b) two-tailed test: df = 18, t = 4.622
