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.

are there two different ways to find the mean? are there two different formulas to find mean? i have an assignmnet that has a formula for mean as Xbar, another one as efx/ef, and another one as xbar=sigma X/n. what are the difference? how do you know which formula to use when you see a question?

The average size of a farm in Kansas is 220 acres. Assume that the data were obtained from two samples with standard deviations of 40 and 15 acres, respectively, and a sample size of 10 and 12, respectively. Can it be concluded with a=0.05 that the average size of the farms in the two states is different? Assume that the population is normally distributed.
