1) For the given information, fill in the table with the critical z-score for each combination of a level and test type. 

Type of Test

alpha level

One-tail

Two-tail

a = .05

z = 1.96

a = .01

a = .005

2) Would a z-score of z = 1.87 result in rejecting H₀ when a = .05 on a 2-tail test.

3) Would a z-score of z = 1.87 result in rejecting H₀ when a = .05 on a 1-tail test.

4) Would a z-score of z = 2.35 result in rejecting H₀ when a = .01 on a 1-tail test.

5) Would a z-score of z = 2.60 result in rejecting H₀ when a = .005 on a 2-tail test.
