Q3: A highway contractor tested the filed bulk density of sub-base; he found that the average bulk density was 2.16 g/cm°, with a standard deviation 0.13 g/cm; one test has been done, determine the probability of: 1. the density of all points is higher than 2.16 g/cm°? 2. the probability of the density is between 2.01 to 2.21 g/cm ?. 3. the probability of the density is higher than 2.25 g/cm?
