The Etruscans. 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 84 preserved Etruscan male skulls was analyzed to help researchers decide whether the Etruscans were native to Italy. The resulting data can be found on the WeissStats site. [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] a. Obtain normal probability plots, boxplots, and the standard deviations for the two samples. b. Based on your results from part (a), which would you be inclined to use to…

An experiment was conducted to study the extrusion process of biodegradable packaging foam. Two of the factors considered for their effect on the unit density (mg/ml) were the die temperature (145 °C vs. 155 °C) and the die diameter (3 mm vs. 4 mm). The results are stored in [Packaging Foam 1]. Source: Data extracted from W. Y. Koh, K. M. Eskridge, and M. A.

1. In many animal species the males and females differ slightly in structure, coloring, and/orsize. The hominidspecies Australopithecus is thought to have lived about 3.2 million years ago. (“Lucy,” the famous nearcompleteskeleton discovered in 1974, is an Australopithecus .) Forensic anthropologists use partial skeletalremains to estimate the mass of an individual. The data below are estimates of masses from partial skeletalremains of this species found in sub-Saharan Africa. Appropriate graphical displays of the data indicate thatit is reasonable to assume that the population distributions of mass are approximately normal for bothmales and females. You may also assume that these samples are representative of the respectivepopulations.Estimates of mass (kg)Males 51.0, 45.4, 45.6, 50.1, 41.3, 42.6, 40.2, 48.2, 38.4, 45.4, 40.7, 37.9, 41.3, 31.5Females 27.1, 33.5, 28.0, 30.3, 32.7, 32.5, 34.2, 30.5, 27.5, 23.3,35.7Do these data provide convincing evidence that the mean estimated masses…
