This model assumes that the sample distribution is symmetric about the mean, M, with a standard deviation, S, and approximates the shape of the bell-shaped curve shown below. Given a value x, this program calculates the probability that a random selection from the sample data will have a higher value. This is known as the upper tail area, Q(x). This program also provides the inverse: given a value Q(x), the program calculates the corresponding value x. y "Upper tail" area Q [x] x x File name 32sii-Manual-E-0424 Printed Date : 2003/4/24 Statistics Programs 16-11 Size : 17.7 x 25.2 cm
