In statistics, the 68–95–99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean, respectively. In mathematical notation, these facts can be expressed as follows, where Pr() … WebThe weight of written reports produced in a certain department has a Normal distribution with mean 60 g and standard deviation 12 g.

WebThe standard deviation for Physics is s = 12. A z score indicates how far above or below the mean a raw score is, but it expresses this in terms of the standard deviation. The z-scores for our example are above the mean. Chemistry z-score is z = (76-70)/3 = +2.00. Physics z -score is z = (76-70)/12 = + 0.50. http://www.seniorwomen.com/news/index.php/gender-wage-gap-widens-even-as-low-wage-workers-see-strong-gains-women-are-paid-roughly-22-less-than-men-on-average エクセル vba トグルボタンオンオフ表示
