Normal Distribution Worksheet
Use this worksheet to explore the concept of probability as area under a normal distribution curve (ยต = 24, sigma = 2). Slide the points x_a and x_b along the horizontal axis to compute the probability P(x_a < x < x_b).
Prove the Empirical Rule (the "68-95-99.7 Rule") to yourself.[br]Which probability is greater: P(23 < x < 25) or P(26 < x < 28)?[br]Do probabilities ever go negative?
Standard Normal Curve Calculator: z-scores
Move the lower (L) and upper (U) sliders to match the z-scores of interest. Observe the area under a standard normal curve.
