Assume that the data has a normal distribution and the number of observations is greater than 50. Find the critical z value used to test a null hyphothesis.

1. alpha symbol = 0.05 for a two tailed test

2. alpha symbol = 0.05 for a left tailed test

3. alpha symbol = 0.1 for a two tailed test

please let me know if my answers are one the right track. Thanks!!

Probably a typo, but alpha for a 1-tailed .05 test should be 1.645

I think you are on the right track.
