Match each Test Situation with the correct Critical Value. For a two-sided test, find only the positive value. Test Situation Two samples, 1 = 25.3, I2 H.: P1 - 2 po, and a 0.01 %3D Two samples, n = 28, Ha: µd > 0, and a 0.01 dv One sample, ni = - 35, п2 41, Ha: p1 – p2 0, and a = 0.01 %3D %3D One sample of x's and y's, n = 114, Ha: p < 0, and a = 0.001 One sample, o is known, n = 68, Ha:µ # Ho, and a = 0.05 One sample, o is unknown, n = 76, H. : µ < Ho, and a 0.05 Critical Value a. 1.960 b. -3.165 C. 2.473 d. 2.326 e. 2.576 f. -1.294 g. -1.665 h. 2.426
