1)understand the use of a normal distribution to model a continuous
random variable, and use normal distribution tables;
solve problems concerning a variable X, where X ~ N, including:
finding the value of P(X > x1), or a related probability, given the
values of x1,
2)finding a relationship between x1, and given the value of
P(X > x1) or a related probability;
3)recall conditions under which the normal distribution can be used
as an approximation to the binomial distribution (n large enou
