95"?!\" What is the area under a standard normal curve between 2 = 2.25 and z = 0? What is the area under a standard normal curve to the left of z = 0.08? What is the area under a standard normal curve between 2 = 0 and z = 2.86? The normal distribution is a type of probability density function. Areas found under this curve are equivalent to probabilities. For example, the probability that 2 lies between a and b is denoted P(a
