Use this worksheet to explore the concept of probability as area under a normal distribution curve (µ = 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.
Which probability is greater: P(23 < x < 25) or P(26 < x < 28)?
Do probabilities ever go negative?
