解析<P>(1) acceptable detection risk = audit risk/the risk of material misstatement s = 10%/80% = 12. 5%</P><P>(2) The upper limit of population deviation rate = Poisson risk factor/sample size = 2. 3/60 = 3. 83 %</P><P>(3) ratio = 156/165 = 94. 54%</P><P>estimate the actual value of the population = 3 000*94. 54% = 283. 62 billion a point estimate of the misstatement in of the population =3 000 -283. 62 *10 = 16. 38 billion</P><P>(4) the expected result of interest income from short-term loan = (300 +320 +310 +300 + 330 +320 +320 +290 +310 +330 +300 +290)*5% =18. 6 billion</P><P>(5) the adjusting accounting entry:</P><P>Dr: Interest suspense 156</P><P>Cr: Interest income 156</P>
