The average length of the right femur of an adult male chimpanzee is #24.65# cm. The variance in this length is #10.24# cm#^2#.
Researchers plan to select a random sample of #25# adult male chimpanzees and measure the length of the right femur of each of them.
What is the expected mean length (in cm) of the right femur for this sample?
