Given the following sample data
 
  Item Group 1 Group 2 Group 3 Group 4
  1 20.9 28.2 17.8 21.2
  2 27.2 26.2 15.9 23.9
  3 26.6 21.6 18.4 19.5
  4 22.1 29.7 20.2 17.4
  5 25.3 30.3 14.1
  6 30.1 25.9
  7 23.8
 
  Based on the computations for the within- and between-sample variation, develop the ANOVA table and test the appropriate null hypothesis using alpha= 0.05. Use the p-value approach.
  A) Since p-value = 0.0678 > 0.05 reject H0 and conclude that at least two population means are different.
  B) Since p-value = 0.000136 < 0.05 reject H0 and conclude that at least two population means are different.
  C) Since p-value = 0.0678 > 0.05 accept H0 and conclude that all population means are the same.
  D) Since p-value = 0.000136 < 0.05 accept H0 and conclude that all population means are the same.
