Answer :
Final answer:
The 68-95-99.7 Rule is a statistical rule that can be used to approximate probabilities for data that follows a normal distribution. It states that approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and approximately 99.7% falls within three standard deviations.
Explanation:
The 68-95-99.7 Rule is a statistical rule that can be used to approximate probabilities for data that follows a normal distribution. It states that:
- Approximately 68% of the data falls within one standard deviation of the mean.
- Approximately 95% of the data falls within two standard deviations of the mean.
- Approximately 99.7% of the data falls within three standard deviations of the mean.
This rule is often used in situations where we have data that is normally distributed and we want to estimate the likelihood of an event occurring within a certain range of values. By knowing the mean and standard deviation of the data, we can use the 68-95-99.7 Rule to quickly estimate the probability.
