RANDOM SAMPLING VERIFICATION OF SIGNATURES <br />The Irvine Support Our Schools Initiative of 2012 <br />V = Number of Valid Signatures <br />A = Value of Each Signature <br />B = Extra Value of Each Duplicate Signature <br />C = B x the Number of Duplicates <br />1. Calculate: <br />l <br />Raw Count (10,007) x Sufficient in Sample (262) = V (5,243.668); rounded to 5,244 <br />Sample (500) <br />2. Divide: <br />Raw Count (10.007) = A (20.014) <br />Sample (500) <br />3. Multiply: <br />A (20.014) x A -1 (19.014) = B (380.546) <br />4. Multiply: <br />B (380.546) x Number of Duplicates (1) = C (380.546) <br />5. Subtract: <br />V (5,244) — C (380.546) = Corrected Value (4,864) <br />The petition is considered qualified, without further verification, if the random <br />sampling determines that the number of valid signatures is over 110% of the <br />number of signatures required. <br />The number of signatures required: 8,738 <br />110% of number of signatures required: 9,612 <br />Random sampling <br />19D -21 <br />am <br />
