Answer:

18

Step-by-step explanation:

So AB has the same proportions as QR. 4 can be multiplied by 2.25 to get to 9. So multiply 8 by 2.25 to get n.

8 * 2.25 = 18 so n = 18

Yuliya22 [10]

Answer: There are 980 degrees of freedom for the within subjects factor.

Step-by-step explanation:

Since we have given that

Number of groups = 20

Number of participants in each group = 50

So, number of participants in 20 groups is given by

20\times 50\\\\=1000

As we know that

Degrees of freedom for the within subjects factor would be

v=n-k\\\\v=1000-20\\\\v=980

Hence, there are 980 degrees of freedom for the within subjects factor.
