... 1. Generate a random sample using rnorm(). Make your sample size somewhere between 1000 and 10000 (e.g., 2487). First generate the z-scores, and then convert to raw scores assuming the population mean is 69 inches and the standard deviation is 2 inches. 2. When the data are recorded, they will be ro ...

... 10. Experiment with the grapher to decide which of the following are true. Mark the true ones. a. If f'(c)=0 then f has a local maximum or local minimum at c. b. A function defined on a closed interval might have a maximum value but no minimum value. c. The absolute maximum of a function might be a ...

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.
