Quizplus · Accepted Answer

In a truly random sample, all members of the population have an equal chance of being selected, regardless of any important characteristics or gender distribution. Therefore, option B is the correct choice. Option A is incorrect as a random sample does not necessarily match subjects on important characteristics. Option C is incorrect as there is no requirement for a specific gender distribution in a random sample. Option D is incorrect because option A and C are not true. Option E is incorrect since option B is true.
