The linear correlation coefficient between a person's age (in years) and their target heart rate (in beats per minute) is approximately \(-0.999\). This indicates a very strong negative linear relationship, meaning that as age increases, the target heart rate decreases.

Would you like further details on this calculation or have any other questions?

Here are five related questions:
1. How does the correlation coefficient relate to the strength of a relationship?
2. Can we interpret causation from this correlation?
3. How do we compute a linear regression line for this data set?
4. What is the significance of a negative correlation coefficient?
5. How does age affect maximum heart rate, and how is it different from target heart rate?

**Tip**: A correlation coefficient close to -1 indicates a nearly perfect inverse relationship, meaning as one variable increases, the other consistently decreases.

Determine the linear correlation coefficient between a person’s age, in years, and that person’s target heart rate, in beats per minute.

Calculate the linear correlation coefficient between age and target heart rate using the Pearson correlation formula. This problem involves statistical analysis to find the relationship between age and heart rate. Suitable for high school students in Grades 10-12.
