Thank you for the opportunity to help you with your question!

. In a 2-tailed test it is necessary to divide alpha by 2, and there are 2 corresponding critical values. If alpha is specified as -1.58, then dividing it by 2 we obtain -0.79 for each tail. At the lower tail, the critical z-value corresponds with P(Z < z) = 0.07. Therefore, z = -1.751. At the upper tail, the critical z-value corresponds with P(Z < z) = 0.96. Therefore, z = 1.751.

Please let me know if you need any clarification. I'm always happy to answer your questions.
