Question

What proportion of subjects in the study were randomly assigned to take st john's wort? explain why this value makes sense?

Answer 1

The proportion of subjects in the study that were randomly assigned to take St. John's wort is about 1/3 or one third. [113 / 338 = 0.334] 0.334 is equivalent to about 1/3.

This value makes sense because the study has 3 treatments, therefore, about 1/3 should be assigned.
