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 List: 10 New Jersey Towns that keep the 'small' in 'small-town' life. Thinking small takes on a whole new meaning in municipalities with as few as five residents. New Jersey is the countryâs fourth-smallest state by land mass but its most densely populated, with approximately 1,200 inhabitants per square mile. Averaging about 15 square miles each, the stateâs 565 municipalities sit fairly close to one another. Some are relatively huge: Newark has about 277,000 inhabitant and Jersey City, 247,000. But as youâll see from this list, there are some very tiny municipalities with unusual provenance.
