| a. | Given the following information, construct an ANOVA table. Use Table 4. (Round intermediate values to 4 decimal places and your answers except \"df\" to 2 decimal places.) |
| SST = 66.03; SSTR = 18.89; c = 4; n1 = n2 = n3 = n4 = 15 |
Solution
a) SS ---- Between Groups = SSTR = 18.89
SS ----- Within Groups = SST - SSTR = 66.03 - 18.89 = 47.14
df ----- Between Groups = c-1 = 3
df ------ Within Groups = n-c = 4*15 - 4 = 56
MS ------ Between Groups = 18.89 / 3 = 6.2967
MS ------ Within Groups = 47.14 / 56 = 0.8417
F = 6.2967 / 0.8417 = 7.48
Fcrt at 10% = 4.15
b) Reject H0 : the population means are not unequal.
---> because Calculated F > Fcrt
