As discussed in class, when we have data that has a symmetric mound-shaped distribution we can use the Empirical Rule to calculate approximate probabilities. Suppose we know the mean of the distribution is 50 with a standard deviation of 10. What is the probability of randomly selecting an observation falling between 40 and da?
