The data in the table below represent the mean, standard deviation, and range of cranial capacity estimates for Homo ergaster/African Homo erectus and Homo erectus/Asian Homo erectus. African Homo erectus/ergaster Asian Homo erectus/ergaster Mean (cc.) Std. Dev. (cc.) Range (cc.) 910 141 804-1067 931 92 815-1059 Do these data suggest that there is a substantial difference between the cranial capacities of the specimens in these two samples? Why or why not?

Step 1
The mean cranial capacity for African Homo erectus/ergaster is 910 cc, while the mean cranial capacity for Asian Homo erectus/ergaster is 931 cc. This suggests that, on average, the cranial capacity of Asian Homo erectus/ergaster is slightly larger than that of Show more…

Homo habilis & Homo erectus compared Apply your knowledge of the early Homo species: Homo habilis is older than Homo erectus. The oldest fossils for both species come from East Africa. Both species exceed the ape cranial capacity threshold of 550. Homo habilis has an average cranial capacity of 680. Homo erectus has an average cranial capacity of 870. Unlike Homo habilis and older hominins, Homo erectus was tall in stature. In a skull-to-skull comparison of these adult specimens: The taller cranium belongs to Homo erectus. The specimen with pronounced brow ridge belongs to Homo erectus. The specimen with the sagittal keel belongs to Homo habilis.

Refer to the sample data given in Exercise $1 .$ Given that the three sample means are $132.7,134.4,$ and $138.1,$ an we use analysis of variance to conclude that the mean skull breadth from 150 A.D. is different from the means in 400 sec. and 1850 s.c? Why or why not?
Analysis of Variance
One-Way ANOVA
Place the following hominins in order from SMALLEST to LARGEST cranial capacity: Homo erectus, Early Homo, Homo heidelbergensis, Homo floresiensis Select one: a. Early Homo, Homo floresiensis, Homo erectus, Homo heidelbergensis b. Homo floresiensis, Early Homo, Homo erectus, Homo heidelbergensis c. Early Homo, Homo erectus, Homo floresiensis, Homo heidelbergensis d. Homo floresiensis, Homo erectus, Early Homo, Homo heidelbergensis
