... A cereal packager is concerned that one of its machines has a mean fill per package or more than 16 ounces, the labelled net weight. While this is not bad from a public relations standpoint, it could cost the packager a great deal of money. Previous experience suggests that the standard deviation of ...

... • What type of data? – Quantitative • What is the population distribution? – No special assumptions. The test refers to the population mean of the quantitative variable. • Which sampling method has been used? – Random sampling • What is the sample size? – Minimum sample size of n=30 to use Central L ...

... Thus, we know the magnitudes of F needed to establish statistical significance at various levels. Table b.7 in Appendix B of Kurtz presents the minimum F ratios necessary for significance at different p levels. The probability associated with an F ratio depends on the degrees of freedom. The two deg ...

... generate. Inferential statistics, as the name implies, infers facts about a large population based only upon facts generated from a (usually) much smaller sample. For example, if we generate an “appropriate” sample of 100 voters in the U.S., we can do a survey, determining the proportion of them who ...
