Question

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(-α / 2 tsta/2)-0.95, where df-17 b. P(ts -ta)0.01, where df 8 C. P(ts-4/2 or tzw2)#0.10, where dfs9 d.PRs-4,2 or tztn/2,-0.01, where dfe8 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 t/2- b. The lower tail critical value t G. The upper tail critical value ta/2 The lower tail critical value w2 d. The upper tail critical value ta/2 The lower tail critical value /2

Answer 1

SolutionA:

use excel enter below

=T.INV.2T(0.95;17)

=0.063638984

=0.064

ANSWER:0.064

SolutionB:

=T.INV(0.01;8)

=-2.896459448

ANSWER:-2.896

Solutionc:

=T.INV.2T(0.1;9)

=1.833112933

upper critical value=1.833

lower critical value=-1.833

Solutiond:

=T.INV.2T(0.01;8)

=3.355387331

upper critical value=3.355

lower critical value=-3.355
