Sagot :
A regression model is used to show the relationship between variables on a scatter plot
- The regression equation is: [tex]\^y = 28.2\^x- 27.9[/tex]
- The likely blood pressure for a patient with sodium intake of 6.0 and 8.5 are 141.3 and 211.8, respectively
How to formulate the regression equation
Using the Microsoft Office Excel, we have the following calculation summary
- Sum of X = 84
- Sum of Y = 2030
- Mean X = 7
- Mean Y = 169.1667
- Sum of squares (SSX) = 2.82
- Sum of products (SP) = 79.4
So, the regression equation is:
[tex]\^y = 28.2\^x- 27.9[/tex]
Blood pressure for a sodium intake of 6.0 and 8.5
This means that x = 6.0 and x = 8.5
When x = 6.0, we have:
[tex]\^y = 28.2 * 6.0- 27.9[/tex]
[tex]\^y = 141.3[/tex]
When x = 8.5, we have:
[tex]\^y = 28.2 * 8.5- 27.9[/tex]
[tex]\^y = 211.8[/tex]
Hence, the likely blood pressure for a patient with sodium intake of 6.0 and 8.5 are 141.3 and 211.8, respectively
