- Can you state the rejection region? Use a .05 level of significance.
Reject H0 if z < 2.28 or z > -1.65
Reject H0 if t > 1.96 or z < -1.96
Reject H0 if z > 1.65 or z < -1.65
d. Reject H0 if z > 1.65
-. Can you state the Null and Alternative Hypothesis? Use a .05 level of significance.
a. H0: = 0.70
H1: 0.70
b. H0: < 0.70
H1: > 0.70
c. H0: 0.70
H1: =0.70
d. H0: > 0.70
H1: < 0.70
a.Reject H0 if z < 2.28 or z > -1.65
