Use what you know about measures of central location and dispersion to answer the following questions:
a. A data set showing sales for the past two months contains only two values. The larger of the two values is 25 units. If the range is 12 units, what is the median number of units sold?
b. In another data set, showing sales for the previous two months, one of the two values is 64 units. If the MAD is 9 units, what is the standard deviation for this data set?
c. If we know that the mean of a two-member data set is 20 and the variance is 16, what are the values in the data set?
