Asked if he has any regrets about the way he's handled the coronavirus crisis so far, President Trump said no — and he cited polling to back him up. Trump has hit his highest approval rating since becoming president – 47% according to an average of the polls. For a random sample of size n = 50 citizens, the standard error of the sampling distribution of citizens support President Trump is [] (four decimal places).
