Descriptive Statistics
... The square root of a variance is called the standard deviation and is positive (unless all values are exactly the same, in which case the standard deviation is zero). The reason for the different divisor (n 1) in the expression for the sample variance s2 will be explained later. The MINITAB output ...

... Some observations specific to this data: 1. Chemical was not significant at alpha = 0.05 because its F-statistic was not larger than the Fcritical for 3 and 12 degrees of freedom. 2. Bolt was significant. The variance between bolts of cloth does matter, even if the type of chemical does not. Bolt's ...

Point estimates are just what the name implies: it is a single point associated with a sample that serves as the estimate of the corresponding parameter. By itself it i ...

... your decision rule in terms of z for rejecting a null hypothesis that the population mean is 500? In this case, each tail must contain 5%, so we look in the middle of the z-table for a value near 0.45, and we find that it corresponds to approximately 1.645 standard deviations from the mean. You can ...
