Textbook Question
Chapter 3, Problem 2E
Some variables, such as height, can be measured directly, and the measurement procedure is usually quite straightforward. Other variables—for example, hunger, motivation, or attitude about the death penalty—are more difficult to measure.
- Describe one procedure that might be used to measure hunger.

- Can you explain what this analysis means in layman's terms? - We calculated that a target sample size of 3626, which was based on anticipated baseline 90-day mortality of 22% and a noninferiority margin of no more than 4 percentage points, would give the trial 80% power, at a one-sided alpha level of 2.5%, accounting for a maximum of 5% loss to follow-up and for early stopping rules for three interim analyses.-arrow_forwardCan you help me understand this analysis? A 95.7% confidence interval is shown for the intention-to-treat analysis (accounting for alpha spending in interim analyses), and 95% confidence intervals are shown for the other two analyses. The widths of the confidence intervals have not been adjusted for multiplicity.
