... • The Poisson distribution was originally used to approximate the binomial distribution for very large numbers of trials, but the Poisson was also found to be good at fitting a variety of random phenomena. • One of the earliest phenomena that was fit using a Poisson random variable was data on Pruss ...

... To access the confidence interval choices, press STAT and select TESTS. The confidence interval choices are found in items 7 through B. Select 7:ZInterval because the population standard deviation, σ, is known. In this example, we have summary statistics, so we will select the STATS option for input ...

... the variation between the sample means that I am witnessing is due to random variation. Look at the Situation where p-value is 0.01. The means for each group are not different. But now the spreads are so close together that I can see clearly that at least one group is different; the green group I wo ...
