I am having trouble with my Statistics Assignment. The problem is listed below. I'm not sure where to start with it.

Periodic assessment of stress in paved highways is important to maintaining safe roads. The Mississippi Department of Transportation recently collected data on the number of cracks (called crack intensity) in an undivided two-lane highway using van-mounted state-of-the art video technology (Journal of Infrastructure Systems, Mar. 1995). The mean number of cracks found in a sample of 8 fifty-meter sections of the highway was, with a standard deviation of 0.105. Suppose the American Association of State highway and Transportation Officials (AASHTO) recommends a maximum mean crack intensity of 0.100 for safety purposes. Can we conclude that the true mean crack intensity of the Mississippi Highway exceeds the AASHTO recommended maximum?
