... b. The plant manager is worried that the drums of Chemical ZX-900 are underfilled . Because of this. she decides to draw a sample of 100 drums from each daily shipment and will reject the shipment (send it back to the supplier) if the average fill for the 100 drums is less than 49.85 gallons.

... The extremes of an attribute are the highest and lowest values, and the range is the difference between them in the units of the attribute. A histogram is a two-dimensional plot of attribute values grouped by magnitude and the frequency of records in that group, shown as a variablelength bar. For a ...

Probability = limiting frequency Probabilities such as P (Higgs boson exists), P (0.117 < as < 0.121), etc. are either 0 or 1, but we don’t know which. The tools of frequentist stat ...
