block sampling-ex pullout the month of june
or
haphazard-no bias, this one or that one
3 factors that affect sample size for attribute sampling
risk of over-reliance-type 2.(this equals (1-confidence) or 90%-inverse
expected deviation(error) rate(variability of population)-direct
tollerable deviation (error) rate(precision)-inverse
in addition to those three the auditor may consider risk of under reliance (implicit)(type 1)-inverse
population size (implicit)-direct
