We can use the separate variances 2-sample t-test. 2-Sample (Independent Samples) t-Procedure Using Separate Variances to Do Inferences for Two-Population Means (Very Different Standard Deviations for the Two Samples). Note: The formulas are provided in the following for your reference only.hen one wants to estimate the difference between two population means from independent samples, then one will use a t-interval. If the sample variances are not very different, one can use the pooled 2-sample t-interval. the degrees of freedom of t is n1 + n2 - 2. Step 1. Find with df = n 1 + n 2 - 2. Step 2.
Wyoming is the smallest state in population, per the census of 2000. Rhode Island ranks 43rd...in other words, seven states are smaller. Source(s): http://www.census.gov/population/cen2000...
