One of the larger species of tarantulas is the Grammostola Mollicone, whose common name is the Brazilian giant tawny red. A tarantula has two body parts. The anterior part of the body is covered above by a shell, or carapace. F. Costa and F. Perez–Miles discussed the carapace length of the adult male G. Mollicone in the article “Reproductive Biology of Uruguayan Therap hosids” (The Journal of Arachnology, Vol. 30, No. 3, pp. 571– 587). The carapace lengths of a random sample of 50 adult male G. Mollicone have a mean of 18.14 mm and a standard deviation of 1.76 mm.
Step by Step Answer:
a Based on the fact that the sample mean is 1814 mm and the sample standard deviation is 176 mm we c...View the full answer
