A standard penetration test (SPT) was performed at a depth of 6.85 ft below the ground surface in a silty sandy soil. Geotechnical tests show the unit weight to of the soil to be 141.0 lb/ft3. The blow counts recorded using a 24 in. sampler were 13/15/20/16. Required Determine the corrected N-value using the CN method, to the nearest whole number.
