Robert Anthony discussion of sampling Digital

The audio recording consists of a lecture about sampling recorded so the speaker, presumably Anthony, can write a book. The speaker notes that the cheapest way to write a book is recording this talk and then editing and revising it. They also introduce two concepts discussed in previous lectures: the notion of frequency distribution and the normal curve or probability. The speaker states the goal of today’s lecture is to join these two concepts together in the context of samples/sampling. They discuss permutations and combinations which help compute probabilities, probability samples, random number tables, sampling as a means for decision making and sequential sampling but spend the majority of the lecture reviewing practice problems and formulas. On second side of the audio tape, the lecture about sampling is continued but ends at 5:17. The speaker talks about standard deviation of the population vs. the deviation of the sample, calculating standard deviation and goes over more practice problems. As noted, the audio gets quiet at 5:17, and a new lecture starts at 6:22. This lecturer discusses the closing of factories, capital assets, bonds and banks.
