Becker Question –

How is that selecting every 12th items gives you a sample of 5% of the population? I don’t recall going reading this in A5 Lecture 1. Can someone clarify or point where in the book it discusses it. Thanks.

It is every 20th item, not every 12th item. If you picked every 20th item out of 100, you would have 5 items, 5/100, or 5%.

FAR - 92 (4/27/12)
AUD - 96 (7/17/12)
BEC - 92 (8/30/12)
REG - 91 (11/12/12)
