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 = 8 b. P (ts - to) = 0.01, where df = 10 c. P(ts -ta/2 or tzta/2 ) =0.10, where of = 7 d. P (ts -ta/2 ort2to/2) =0.01, where df = 16 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 = b. The lower tail critical value to = ] c. The upper tail critical value to / 2 = The lower tail critical value to /2 = 0 d. The upper tail critical value to/2=] The lower tail critical value to/2=
