I get the same results in Mathematica v 8.0.4.0


$Version


"8.0 for Mac OS X x86 (64-bit) (October 5, 2011)"


data = {{15000, 0.154}, {25000, 0.283}, {35000, 0.402}, {50000, 0.55},
{75000,
     0.733}, {100000, 0.843}};


nlm01 = NonlinearModelFit[data,
   CDF[ParetoDistribution[khat, ahat], $x], {khat, ahat}, $x];


nlm01["BestFitParameters"]


{khat -> 12989.3, ahat -> 0.658768}
