Falls/ does not fall, Reject/do not reject, Provide/do not provide Consider the data in the table collected from three independent populations. Sample 1 Sample 2 Sample 3 III a) Calculate the total sum of squares (SST) and partition the SST into its two components, the sum of squares between (SSB) and the sum of squares within (SSW) b) Use these values to construct a one- way ANOVA table c) Using a 0.05, what conclusions can be made concerning the population...
