Determine the appropriate critical value{s) for each of the following tests concerning the population mean: a. upper-tailed test: 0: = 0.025; n = 25; o = 3.0 b. lower-tailed test: a = 0.05; n = 29; s = 7.0 c. two-tailed test: 0: = 0.01; n = 31; s = 4.1 d. two-tailed test: (I = 0.20; n = 36; o = 3.7 a. Determine the appropriate critical value for an upper-tailed test: on = 0.025; n = 25; cr = 3.0. The critical value{s) is(are) . (Round to two decimal places as needed. Use a comma to separate answers as needed.) b. Determine the appropriate critical value for a lower-tailed test: on = 0.05; n = 29; s = 7.0. The critical value{s) is(are) . (Round to two decimal places as needed. Use a comma to separate answers as needed.) c. Determine the appropriate critical values for a two-tailed test: or = 0.01; n = 31; s = 4.1. The critical value{s) is(are) . (Round to two decimal places as needed. Use a comma to separate answers as needed.) d. Determine the appropriate critical values for a two-tailed test: or = 0.20; n = 36; o = 3.7. The critical value{s) is(are) . (Round to two decimal places as needed. Use a comma to separate answers as needed.)
