A 96% confidence interval for the mean is reported as (0.8, 2.3) for a set of data. Suppose we want to conduct a two-sided significance test with the null hypothesis Ho: μ = 0 using the computed confidence interval. 1) What level of significance would be used in the test of significance ? 2) Are the results statistically significant? Fully justify why/why not.

The commonly used critical Z values are 1.645 for a 90% confidence interval (or 2-tailed, .10 level of significance), 1.96 for 95% confidence and 2.58 for 99% confidence. If a different confidence level is required, such as 92%, how can you determine the critical Z value? What is the relationship between the confidence level and the level of significance of a 2-tail test? Which Hypothesis Tests use Z distributions? Which Hypothesis Tests use a Student’s t distribution? Which Hypotheses Tests...
