They aren't independent random variables, they're all in the same geographic area, how can you know one bad shipment wasn't brought to where Twesterm lives?

Because the variability of the sample is likely to be small between batches, Sony does their own testing as well to prevent bad batches from leaving the factory. Because the are all produced in the same way using the same methods on the same equipment the expected variability between batches would be small anyway. Im tired, I hardly slept last night and statistics is my worst subject TBH. I can't argue anything stronger than this.



Tease.
