Find the P-value for the indicated hypothesis test with the given standardized test statistics z. Decide whether to reject Ho for the given level of significance a. 1. Left-tailed test, z=-1.32, a=1.10 2. Right-tailed test, z=2.46, a=0.01 3. Two-tailed test, Z=-1.68, a=0.05 In exercises 4-8, match each P-value with the graph that displays its area. The graphs are labeled (a)-(d) 4. P=0.0089 5. P=0.3050 6. P=0.0688 7. P=0.0287 (a) (b) -2 2 -3 /-2 -1 0 2 3 Z = 1.90 z =-2.37 (c) (d) -2 3 -3 -2 -1 2 3 z = 1.82 Z=-0.51
