You have graduated from college and have been working hard to get established in your field. You eventually land a perfect job where you make tons of money. You decide to step up from the 1992 Chevrolet Cavalier that you have been nurturing for a number of years into a more "comfortable" car (a.k.a. more expensive). You decide t

Normal probability distribution (bell curve)

1. Draw a normal probability distribution (bell curve) on a piece of paper and mark the center line (mean). (no need to send me the sketch-just tell me your answer. a. Draw another line to the right of the center and call it x. If you want to know what the value of the area "greater than" x is, would you be looking to the area
