Mean Value Calculation
1. Regression Equations:
- x = 19.13 - 0.87y
- y = 11.64 - 0.5x
2. Finding Mean Value:
- To find the mean value, we need to calculate the average of x and y values based on the regression equations provided.
3. Mean Value of x:
- Substitute y = 0 in the equation x = 19.13 - 0.87y
- x = 19.13 - 0.87(0)
- x = 19.13
4. Mean Value of y:
- Substitute x = 0 in the equation y = 11.64 - 0.5x
- y = 11.64 - 0.5(0)
- y = 11.64
5. Mean Value Calculation:
- Mean value of x = 19.13
- Mean value of y = 11.64
6. Explanation:
