For each of the following data sets, construct a graphical display of the data distribution and then indicate what summary measures you would use to describe center and spread. a. The following are data on weekend exercise time for 20 females consistent with summary quantities given in the paper "An Ecological Momentary Assessment of the Physical Activity and Sedentary Behaviour Patterns of University Students" (Health Education Journal [ 2010]: 116 - 125).

b. The accompanying data are consistent with summary statistics that appeared in the paper "Shape of Glass and Amount of Alcohol Poured: Comparative Study of Effect of Practice and Concentration" (British Medical Journal [ 2005]: 1512-1514). Data represent the actual amount (in ml) poured into a tall, slender glass for individuals asked to pour a "shot" of alcohol (44.3 ml or 1.5 ounces).

c. The accompanying data are from a graph that appeared in the paper "Ladies First? A Field Study of Discrimination in Coffee Shops" (Applied Economics [ April, 2008]). The data are the wait times ( in seconds) between ordering and receiving coffee for 19 female customers at a Boston coffee shop.
