Mean: nxmin ≤ ∑ x so dividing by n yields xmin ≤ ˉx, so the minimum value is not above average. Median: the middle measurement, or average of the two middle measurements, ˜x, is at least as large as xmin, so the minimum value is not above average.The question: can you convert a PDF to a Microsoft Word doc file?
