According to a random sample taken at 12 AM, body temperatures of healthy adults have a bell-shaped distribution with a mean of 98 17°F
According to a random sample taken at 12 AM, body temperatures of healthy adults have a bell-shaped distribution with a mean of 98 17°F and a standard deviation of 0.61°F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 2 standard deviations of the mean? At least % of healthy adults have body...

urgent solution needed
- A contractor wants to design a flexible pavement which has a 4-inch sand-mix asphalt wearing surface, 11-inch soil cement base, and a 11-inch crushed stone subbase. It is designed to withstand 400 22-kip single-axle loads and 800 34-kip tandem axle loads per day. The subgrade CBR is 8, the overall standard deviation is 0.45, the initial PSI is 4.2, and the final PSI is 2.5. What is the probability that this pavement will have a PSI...
