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 smallest nation is Vatican City, which has a population of under 1000 and has a Swiss Guard regiment of 110. Nauru is also fairly small, having a population of 10000 and 23 guns among 100 police officers. If the country from 1000 years ago were placed geographically adjacent to the modern one, the country from 1000 years ago would definitely win. There is only so much ammo the Swiss guards ...
