Wondering why A.) is incorrect. Seems like a flaw to me is that a sample's percentage of defective products does not guarantee the rate of defective products as a whole is above the stipulated rate. Isn't this what A.) is saying? I suppose A is inadequate because we do NOT know the size of the sample is small as it suggests. Still, if you figure any sample is necessarily not able to tell us with absolute certainty the percentage of defective products, it seems like concluding the contract was violated is a flaw because we don't know for sure the percentage of defective products.

I can see why TCR is correct, and I think it matches the fundamental flaw I was looking for in the ACs/saw in the stimulus (that the samples may not be representative of the actual rate of defective products). Just wondering if you all had any thoughts.

Thanks.
