Math Problem Statement
Use power regression to find a power function that best fits this data. Enter your equation below. Round all values to 3 decimal places
x 6 7 8 9 10 11 y 1604 2058 2324 2778 3427 4118
Solution
Power regression finds a relationship in the form , where and are constants to be determined.
To solve this, I will:
- Linearize the data by taking the logarithms of both and .
- Apply linear regression on the transformed data.
- Convert back to the power form.
Let's go through the steps. I will calculate this equation for you.The power function that best fits the given data is:
Would you like more details on how this was calculated or have any other questions?
Here are five related questions for further exploration:
- How would the power function change if we extended the data range?
- Can power regression be applied to any type of data, or are there specific conditions?
- How does power regression compare to exponential or polynomial regression?
- What are the real-world applications of power functions in modeling data?
- How does the correlation coefficient affect the interpretation of the power model?
Tip: When interpreting regression models, always check the residuals to ensure the model fits the data well.
