Find th range, mean, variance, and standard deviationof the sample sata set:
19 20 17 21 21 21 19 18 19 19
17 17 15 18 18 18 18 17 17 17
Range:
Sample mean, round to the nearest hundredth
Sample variance (use unrounded values to find the answer, round to the nearest hundredth)
Sample standard deviation (use unrounded values to find the answer, then round to the nearest hundredth)
The Excel file contains formulas and calculations of the range, mean, variance, and standard deviation of the sample data set.
