1000 μg is needed to make a milligram, so we have less than one (μg to mg: shift the decimal point three places to the left).Note: The following three questions about the “central tendency” of data rely on the following information. Consider the weekly earnings in dollars for ten workers to be 400, 475, 475, 475, 500, 500, 525, 620, 630 and 660. These ten wages add to the total of $5260.
