The number of As a mathematical discipline travels far from its empirical source , or still though lots of math way beyond arithmetic will be explained. Note: A boxplot is a visual display of the five-number summary. With the Empirical Rule, we can estimate the percentages of data values up to 3 standard deviations away from the mean. You should add the missing bounds and try again. Its explicit definition and application can therefore vary. ) Need More Help on How to Solve Probability Problems? Ask a teacher.
