What is a Random sample poll?
A random sample is a sample that is collected without any specific characteristics in mind. For instance, instead of collecting a sample of women or members of a particular age group, they are collected randomly off the streets.

Can one correct for bias by using a large sample?
Large samples can be just as biased as small samples, depending upon how they are selected. For example, you want to do a survey to see how popular the President is, but you only interview men, refusing to interview women. No matter how many men you interview, this bias still exists. A sample of a million men is still biased if you have excluded women. (Although the data are still significant as long as you recognize that the bias exists.)
Should a woman be in the pulpit?
There is no specific edict against women in the pulpit; the specific reference "...and women should be silent in church," is generally considered to mean "don't chatter." In fact the etymology of the word indicates 'chattering.'
