The average weekly incomes, in £s, of 18 selected occupations in the United Kingdom were: 244, 146, 278, 396, 435, 641, 577, 122, 294 357, 802 730, 286, 484, 169,, 559, 208, 498     Find the median, mode, variance, range, mad, upper extreme, lower extreme.  Draw a box plot to represent these incomes.  Calculate the mean weekly income and the standard deviation.  (HANDWRITTEN OR AT LEAST NOT IN A CODE FORM)
