Assume that the data has normal distribution and the number of observations is greater than fifty: Find the critical z value used to test null hypothesis- a =0.05 for a two tailed test: A) ±1.764 B) ±1.645 C) ±2.575 D) ±1.96

Assume the population has a normal distribution and the number of observations in a random sample is greater than fifty. If a z-test is used to test a null hypothesis about the population mean versus the alternative that the true mean is greater than that specified by the null hypothesis, what is the critical value for a one-tailed test? Assume the type one-error rate is 0.05. A) +2.052 B) +1.645 C) +2.576 D) +2.33
