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...

Rhode Island earned the nickname the âOcean Stateâ for its 400 miles of swirling, saltwater coastline, carving out Narragansett Bay and inlets up to the Massachusetts border. âLittle Rhodyâ is also the smallest state in the U.S â only 1,500 square miles â and it is a 30-minute drive from any geographic point to the waterline.
