## Document Summary

Quiz 2 covered materials in: chapter 5, chapter 6, chapter 7 p. Normal distribution is symmetrical and bell shaped, implying that most values tend to cluster around the mean, equal to median. The uniform distribution is symmetrical and therefore the mean = median. The focus is on a continuous, bell-shaped distribution distribution. 4 the tails of the normal curve extend to infinity: the tails of the normal curve extend to infinity in both directions and never touch the horizontal axis. B < x < +b: however, the tails get close enough to the horizontal axis quickly enough to ensure that the total area under the normal curve equals. When a mathematical expression is available to represent a continuous variable, the probability that various values occur within certain ranges or intervals can be calculated. www. notesolution. com. However, the exact probability of a particular value from a normal. The normal probability distribution is defined by the equation f(x)
