A standard penetration test has been conduted at a depth of 15 ft in an 8-inch diameter exploratory boring using a USA-style safety hammer and a standard sampler. This test produced an uncorrected N-value of 12. The soil inside the sampler was a fine-to-medium sand with Dsq = 0.6 mm. The vertical effective stress at this depth is 1100 lb/ft². Adjust the N- value as described in Class handout, then compute the relative density and classify the soil using Table 3.3.
