Below are some of the common mistakes I found on your AP Statistics homework and exams; please make sure you do not make the same mistakes:
When we calculate the probability of a random variable X of a certain distribution, P(a<X<b) is the area under the curve between a and b. The probability of X taking a specific value P(X=x) is zero. The calculator function normalpdf DO NOT give you the probability of P(X=x), instead it gives you the y position of the curve at x.
