President Donald Trump on Thursday announced a new round of punishing tariffs, saying the United States will impose a 100% tariff on imported branded drugs, 25% tariff on imports of all heavy-duty trucks and 50% tariffs on kitchen cabinets.
Trump also said he would start charging a 30% tariff on upholstered furniture next week.
A good rule of thumb in statistics is that a sample size of about 30 will give you some idea of the standard deviation. Anything less than that, and your analysis is on shaky ground. In logistics terms, all you need to get started is just one truck load of anti-vaxxers.
