How to Compare Two Population Proportions - dummies

If you’re running an F Test using technology (for example, an ), the only steps you really need to do are Step 1 and 4 (dealing with the null hypothesis). Technology will calculate Steps 2 and 3 for you.

Examples demonstrating how to use Excel functions to perform hypothesis testing using the binomial distribution.

Question 3: Some students who belong to Greek organizations (e.g. fraternities and sororities) believe that they do not drink anymore or less than non-Greek-organization students. However, the university administration does not agree, and wants to show that on average, the population of Greek students drink more more frequently during any given month than their non-greek counterparts. What would be the correct hypothesis to determine if the administration is correct? Assume that non-greeks are population and greeks are .

NOTE: This was a two-sided test since we used "not equal" in the alternative hypothesis (also see that says "not = 0"). If the research interest was to show that on average right-hand spans were longer than left-hand spans then our new Ha would use > and we need to divide this p-value by 2. In then next example we show how to use minitab to conduct such one-sided hypothesis tests.

Hypothesis testing of the difference between two population means ..

The following summarizes population and sample notation for comparisons, and gives the null hypothesis for each situation (proportions and means).

Two Sample Hypothesis Testing to Compare Variances | …

NOTE: The use of "0" for the difference is common practice. Technically however this difference could be any value. For example, we could say that the difference between the percentage of males that smoke to the percentage of females that smoke is equal to 4%. Now the null hypothesis would read: H0: p1p2 = 0.04. For our class we will restrict ourselves to using a difference of 0.

In order to make this comparison, two independent (separate) random samples need to be selected, one from each population. The null hypothesis H0 is that the two population proportions are the same; in other words, that their difference is equal to 0. The notation for the null hypothesis is H0: 1 = 2, where 1 is the proportion from the first population, and 2 is the proportion from the second population.
