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.-

A business office orders paper supplies from one of three vendors, V₁, V2, or V3. Orders are to be placed on two successive days, one order per day. Thus, (V2, V3) might denote that vendor V2 gets the order on the first day and vendor V3 gets the order on the second day. (a) List the sample points in this experiment of ordering paper on two successive days. (b) Assume the vendors are selected at random each day and assign a probability to each sample point. (c) Let A denote the event that the same vendor gets both orders and B the event that V2 gets at least one order.
