I'm kind of confused with these testbook questions and was wondering if someone could walk me through them:
1. Find the approciate rejection regions for the large-sample test statistic z in these cases:
a. A left-tailed test at the 1% significance level.
b. A two-tailed test with α = 0.01
2. Find the p-value for the following large-sample z tests:
a. A right-tailed test with observed z = 1.15
b. A two-tailed test with observed z=-2.78
c. A left-tailed test with observed z=0.81
