Answer to Question 1

Because the binomial distribution has gaps between possible values of x (since it is discrete), while the normal distribution is continuous, the normal approximation to the binomial involves a correction for continuity. The correction consists of expanding each possible value of the discrete random variable x by 0.5 in each direction.
