The article "Characteristics and Trends of River Discharge into Hudson, James, and Ungava Bays, 1964-2000" (S. Dery, M. Stieglitz, et al., Journal of Climate, 2005:2540-2557) presents measurements of discharge rate x (in kmlyr) andpeakflow y (in m/s) for 42 rivers that drain into the Hudson, James, and Ungava Bays.

The Wind Mountain excavation site in New Mexico is an important archaeological location of the ancient Native American Anasazi culture. The following data represent depths (in cm) below surface grade at which significant artifacts were discovered at this site (Reference: A.I. Woosley and A.J.

The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Here are data for beak heat loss, as a percent of total body heat loss from all sources, at various temperatures in degrees Celsius.

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…
