... • Central limit theorem – For any population with a mean (M) and a standard deviation (SD), the distribution of means (DOM) for sample size n will approach a normal distribution with a mean of M and an SD = PopulationSD / Sqrt(n) • For samples of n=30 or more, the DOM will be almost perfectly normal ...

... b. As a class, compile the means for the sample of 25 people. Determine the mean and standard deviation of this set of means. That is, calculate x and x . How does the mean of the sample means compare with the population mean? How does the standard deviation of the sample means compare with the ...

... (a) Is the average ROE in 1998 significantly different from that in 1999? Carefully state the hypotheses that you are testing and the test(s) that you are using, being sure to justify your choice(s). (b) Is there any reason to doubt the results in part (a)? If so, what would you do to try to answer ...

... Of course, this is based on the usual formula X ± t.025 t-critical value of 1.98326 (based on 103 degrees of freedom), but if you used 1.984 (based on df = 100) you will get the virtually identical answer (1.4577, 1.6571) This is in thousands of square feet, of course, so this is (1458, 1657) square ...

German tank problem
In the statistical theory of estimation, the problem of estimating the maximum of a discrete uniform distribution from sampling without replacement is known in English as the German tank problem, due to its application in World War II to the estimation of the number of German tanks.The analyses illustrate the difference between frequentist inference and Bayesian inference.Estimating the population maximum based on a single sample yields divergent results, while the estimation based on multiple samples is an instructive practical estimation question whose answer is simple but not obvious.
