What is the minimum number of tests to achieve statistical significance?I'm dealing with a situation where in a large manufacturing facility we have approximately 2000 plumbing fittings of the same make and model. 3 of those fitting have failed within the last year. Each causing major property damage. We suspect that the plumbing components suffered degradation and we want to test a sample of the remaining plumbing components to see how wide spread the issue is (if at all).What is the best way to decide how big of a sample we should choose so that we do not under test or over test the installed components.Any idea where to begin?
Show that an exponential model fits the data. Then write a recursive rule that models the data.
What are logarithms?I have heard of logarithms, and done very little research at all. From that little bit of research I found out its in algebra 2. Sadly to say, I'm going into 9th grade, but yet I'm learning [calculus!?] and I don't know what a logarithm is! I find it in many places now. I deem it important to know what a logarithm is even though I'm jumping the gun in a sense. My understanding of concepts, is just like that of programming. In the mean time, you know its there, and your ITCHING SO HARD to find out what that is, but nope! For now we use it, tomorrow we learn what it does.I just know that to identify a logarithm at my level, I just look for a log. :P
