The lifespans of zebras in a particular zoo are normally distributed. The average zebra lives 20.520.520.5 years; the standard deviation is 3.93.93.9 years. Use the empirical rule (68-95-99.7\%)(68−95−99.7%)(68-95-9 9.7%) to estimate the probability of a zebra living between 16.616.616.6 and 24.424.424.4 years.
