Look at the bell-shaped curve of the Normal Distribution: Why does neither end touch zero?

For a symmetrical bell-shaped curve, - the probability of a data point being within +/- one standard deviation is 68%. - the probability of a data point being within +/- two standard

A ___ is a continuous distribution that is bell-shaped and symmetrical around the mean. A. Exponential distribution B. Normal distribution C. Uniform distribution D. Binomial distribution

The empirical rules states that: a. .% of data in symmetrical distribution will fall within one standard deviation of the mean. b. .% of data in symmetrical distribution will fall within two

1. The Empirical Rule applies only to approximately normal or bell-shaped distributions. 2. The Empirical Rule states that approximately 65% of the data lies within one standard deviation of the mean, 98%

SOLVED: The Empirical Rule says that for bell-shaped symmetric distributions, approximately 68% of the data fall within one standard deviation away from the mean. Where is this number 68% coming from? For
