The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 Ib. Assuming that o is known to be 121.2 Ib, use a 0.10 significance level to test the claim that the population mean of all such employees weights is less than 200 lb. Identify the null and alternative hypotheses. Ο H0: μ < 200 H1: 4 > 200 O Ho: 4 200 H1: µ # 200 O Ho: µ 200 %3D H1: µ < 200 O Ho: 4 = 200 H1:µ > 200

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.
