1. If the variance is known, the sample is 800, and the level of significance is 0.01, what is the critical value if one tailed-test will be used? 2. If the variance is unknown and the sample is 15, what is the critical value if one-tailed test willI be used at 0.01 significance level? 3. If the variance is unknown, the sample is 27, at 0.10 significance level, what is the critical value if two-tailed test will be used?
