Anthropologists are still trying to unravel the mystery of the origins of the Etruscan empire, a highly advanced Italic civilization formed around the eighth century B.C. in central Italy. Were they native to the Italian peninsula or, as many aspects of their civilization suggest, did they migrate from the East by land or sea? The maximum head breadth, in millimeters, of 70 modern Italian male skulls and that of 84 preserved Etruscan male skulls were analyzed to help researchers decide whether the Etruscans were native to Italy. The resulting data can be found on the WeissStats CD. [SOURCE: N. Barnicot and D. Brothwell, “The Evaluation of Metrical Data in the Comparison of Ancient and Modern Bones.” In Medical Biology and Etruscan Origins, G. Wolstenholme and C. O’Connor, eds., Little, Brown & Co., 1959]

Katie Vote owns a small business that rents computers to students at the local university for the 9-month school year. Katie’s typical rental contract requires the student to pay the year’s rent of $1,800 ($200 per month) in advance. When Katie prepares financial statements at the end of December, her accountant requires that Katie spread the $1,800 over the 9 months that a computer is rented. Therefore, Katie can recognize only$800 revenue (4 months) from each computer rental contract in the year the cash is collected and must defer recognition of the remaining $1,000 (5 months) to next year. Katie argues that getting students to agree to rent the computer is the most difficult part of the activity so she ought to be able to recognize all$1,800 as revenue when the cash is received from a student.
