Question 1076054
The significance level is alpha=0.05, which means that if it is 2-sided, the probability is 0.025 on each side, and the p-value for a z-1.36 is 0.1738 for a two sided test BUT 0.0869 for a 1 sided test, where the entire rejection region is on one side of the curve.  
The critical values are |z|>1.96 for a two sided test and |z|>1.645 for a 1-sided test.
