To understand the grounds for confidence realize that there are only two possibilities: 1. The interval between 452 and 470 contains the true . 2. Our SRS was one of the ...

Because observing such a sample mean would occur by chance only 4.56% of the time if the null hypothesis, μ=454g, is true. In summary, we have obtained the following precise criterion for deciding whether to reje ...
