... 10 pieces of paper is selected each hour from the previous hour’s production and a strength measurement is recorded for each. The standard deviation σ of the strength measurements, computed by pooling the sum of squares of deviations of many samples, is know to equal 2 pounds per square inch, and th ...

If simple random sampling (every observation has the same chance of being selected) is used to select n from N, then: Sample estimates are unbiased estimates of their counterparts (e.g., sample mean estimates the population mean), meaning that over all possible samples the sample statistics, avera ...

Geometric Distribution
... A distribution has a specified number of independent trials with two possible outcomes, or . The random variable is the number of unsuccessful outcomes before a success occurs. Note that the number of trials prior to the first success is called the before success. ...
