Probability in a normal distribution
WebbWe just type a one-line command in Excel and we get the probability we care about. So, let me wrap up this lecture. We talked about the famous bell curve, which is the density function or the graph of the density function of the normal distribution. And calculations of those probabilities from the normal distribution is really easy. WebbQuestion 2 When discussing the normal distribution, the standard normal probability distribution I. has a mean equal to 1 and a standard deviation equal to 0. II. can be converted from any normal distribution using a formula. III. measures the distance from the mean in units of the standard deviation. I only II and III only I and II only I, II ...
