K Use your calculator to find critical values such that the following statements are true. Your task is to determine the critical values below. a. P( -ta/2 ststa/2 ) =0.95, where df = 11 b. P (ts - to) =0.01, where df = 12 c. P(ts -ta/2 or tzto/2 ) =0.10, where df = 8 d. P (ts - ta/2 or tzta/2) =0.01, where af = 19 Click the icon to view the table of critical values of t. (Use 3 decimal places in all questions please.) (Use 3 decimal places in questions a-d please.) a. The upper tail critical value to/2 = 2.200 b. The lower tail critical value to = - 2.681 c. The upper tail critical value to/2 = 1.130 The lower tail critical value to/2 - - 1.130 d. The upper tail critical value to/2 = 0.127 The lower tail critical value to/2= -0.127 Clear all structor
