4. Refer to Exhibit 1-1. The number of degrees of freedom corresponding to between treatments is a. 18 b. 2 c. 4 d. 3

5. Refer to Exhibit 1-1. The number of degrees of freedom corresponding to within treatments is a. 22 b. 4 c. 5 d. 18

6. Refer to Exhibit 1-1. The mean square between treatments (MSTR) is a. 36 b. 16 c. 64 d. 15

Solution

4.) Mean square within = SS within/df

Therefore, df = (100 - 64)/ 2 = 18

5.) F = MS between/ MS within

Therefore MS between = 8*2/= 16

df between = SS between/ MS between = 64/16 = 4

6.) MS between = 16
