Answer: The value for Z are as follows:
Explanation:
The area under the standard normal curve that lies to the left are as follows:
(a) Z=0.83 = 0.7967
(b) Z=0.06 = 0.5239
(c) Z=−0.57 = 0.2843
(d) Z=−1.33 = 0.0918
All the Z-critical values represents the area towards the left. A critical value also shows the rejection region for the hypothesis testing.
