Final answer:
The empirical rule can be used to estimate the probability of a lion living longer than 7.2 years, but we need the mean and standard deviation of a lion's lifespan.
Step-by-step explanation:
The empirical rule can be used to estimate the probability of a lion living longer than 7.2 years. According to the empirical rule, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.
To estimate the probability of a lion living longer than 7.2 years, we can calculate the z-score using the formula z = (x - mean) / standard deviation. From the given information, we need to know the mean and standard deviation of a lion's lifespan to use the empirical rule. Without that information, we cannot apply the empirical rule to estimate the probability of a lion's lifespan.
