1. True or False? A clinical trial is conducted to compare an experimental medication to placebo to reduce the symptoms of asthma. One hundred participants are enrolled in the study and randomized to receive either the experimental medication or placebo. The primary outcome is self-reported reduction of symptoms. Among 50 participants who receive the experimental medication, 30 report a reduction of symptoms as compared to 15 participants of 50 assigned to the placebo. The 95% CI for the relative risk of participants reporting a reduction of symptoms between the experimental and placebo groups is between 0.114 and 0.486.

2. True or False? When calculating a confidence interval for one sample with a continuous outcome and the sample contains greater than 30 individuals, then a t-score should be used in place of a z-score.

3. True or False? The Confidence Interval is the product of the value that reflects the desired confidence level (e.g.,Z= 1.96 for 95% confidence) and the standard error of the point estimate.

4. True or False? The 95% Confidence intervals for relative risks and odds ratios require the usage of the natural log in their formula
