A company that produces snack foods uses a machine to package 454g bags of pretzels. The hypotheses are as follows: Ho : µ = 454g (the packaging machine is working properly) Ha : µ ≠ 454g (the packaging machine is not working properly) Suppose that the results of the sampling lead to non-rejection of the null hypothesis. Classify the conclusion as a Type I Error, Type II Error, or a correct decision, if in fact the mean net weight is not equal to 454g.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
