Statistically Dubious

The CBC weighs in on the current trade spat between China and the US.
Chinese government inspectors have concluded tires made by a Chinese company that is the subject of a huge U.S. recall meet official U.S. safety standards, news reports said Wednesday.

Officials issued the decision after inspecting the Hangzhou Zhongce Rubber Co. and testing three tires at a government laboratory, China Daily, the Oriental Morning Post and other newspapers reported.

Now, I don't know as much statistics as I should, but I do know that regardless of what distribution you're assuming the tires to come from, a sample size of three is not sufficient to "prove" anything at any level of significance.
