Acetone is also very useful because it is miscible (mixable) with all common solvents and water and thus most common paints, finishes and coloring products. So acetone can be added in significant percentages to most of the coating materials we use. Also important, acetone is the fastest evaporating and one of the strongest of all commonly available solvents and it is very dry (non-oily). So it makes an excellent cleaner and degreaser and this is how it is used in most other industries.
The standard form of any distribution is the form that has location parameter zero and scale parameter one. It is common in statistical software packages to only compute the standard form of the distribution. There are formulas for converting from the standard form to the form with other location and scale parameters.
A statistic used to estimate a population parameter is unbiased if the mean of the sampling distribution of the statistic is equal to the true value of the parameter being estimated. Note that. The mean of the sample means (4) is equal to m, the mean of the population P.
