The shape of this distribution is ______. a. symmetric b. bimodal c. right skewed d. left skewed e. normal

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

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

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%

IQ scores have a bell-shaped distribution with a mean of 100 and a standard deviation of 15. Draw the distribution.

The shape of this distribution is ______. a. symmetric b. bimodal c. right skewed d. left skewed e. normal

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
