having a hard time trying to get some of these extra credit and review problems. hope you can help!

e7,5.6, and la a isgt $a8a ANd0ppaioun, thr anale .5., nd 6. IfSST=65.27 and SSTr-23.49, then the teststatistic valuefis a. 3.75 b. 2.09 c. 7.83 d. 0.56 e. 6.67

Solution

Thus, as df1 = k - 1 = 3,

MSTr = SSTr/df1 = 23.49/3 = 7.83

Also,

SSW = SST - SSTr = 65.27-23.49 = 41.78

Thus, as N = 7+5+6+6 = 24, and df2 = N - k = 24 - 4 = 20

MSW = SSW/df2= 41.78/20 = 2.089

Therefore,

F = MSTr/MSW = 7.83/2.089 = 3.748204883 = 3.75 [ANSWER, A]
