Answer:
N=27 participants
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
When we conduct a multiple regression we want to know about the relationship between several independent or predictor variables and a dependent or criterion variable.
If we assume that we have
independent variables and we have
individuals, we can define the following formulas of variation:
And we have this property
The degrees of freedom for the model on this case is given by
where k =2 represent the number of variables.
The degrees of freedom for the error on this case is given by
. Sinc we know k we can find N.
![N=24+k+1=24+2+1=27](https://tex.z-dn.net/?f=N%3D24%2Bk%2B1%3D24%2B2%2B1%3D27)
And the total degrees of freedom would be ![df=N-1=27 -1 =26](https://tex.z-dn.net/?f=df%3DN-1%3D27%20-1%20%3D26)
On this case the correct answer would be N=27 participants
