Data relative to three MPU estimation plans are presented below.

$\backslash$table$[[,1,2,3],[$Tolerable misstatement,$$110,000,$$$140,000,$$$170,000],[$Size of population,$5,000,6,000,8,000],[$Risk of incorrect rejection,$10\%,5\%,10\%],[$Estimated population standard deviation,$$80,$$$105,$$$125],[$Risks that misstatements accumulating to greater than tolerable misstatements will not be detected by:$,,,],[$Internal control,$50\%,40\%,40\%],[$Other substantive procedures $($excluding this test of details$),25\%,50\%,85\%],[$Desired overall audit risk,$5\%,5\%,5\%],[$Inherent risk,$100\%,100\%,100\%]]$
