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...
The following table lists the population of each state in the United States, from the year 1790 to 2015. From 2000 to 2010, Nevada grew the fastest, followed by Arizona, Utah, Idaho and Texas. Louisiana, Ohio, and Rhode Island had the slowest increase in population. Michigan was the only state to experience a population decline over the decade, losing 0.6% of its population.
