Apparently this was supposed to be announced at the weekend , but he let it slip . <| sep |> And I can think you are a brainwashed propoganda filled fool for thinking trump is racist . While hillary was getting shit for being in a whites only country club , trump was buying country clubs in Florida that banned black people and jews , and forcing them to allow all people to join . Seriously , anyone saying trump is racist is an ignorant koolaid drinker . Edit not by spez down vote all you want , doesn ' t change history . Hillary is a racist piece of shit . Trump is not . Stay salty , ignorant fools . Notice how no one is disputing Hillary ' s blatant racism . Haha , fucking rich . <| sep |> Your formula for z score is incorrect . The formula for z score is valuemeanstandard deviationYour z score value for 21 makes no sense because for a value bigger than the mean 20 . 8 , the probability should be bigger than 0 . 5 . Z score for 21 should be 2120 . 83 . 1 0 . 06 0 . 5239 probabilitySo for 16 it would be 1620 . 83 . 1 1 . 55 0 . 0606 probabilitySubtracting the two probabilities since you want to find the probability of it being between 16 and 21 should be 0 . 5239 0 . 0606 will yield 0 . 4633 probability , which should be your final answer
