Independent random samples were selected from three populations, shown in the table below:

sample 1	sample 2	sample 3
2.1	4.4	1.1
3.3	2.6	0.2
0.2	3.0	2.0
	1.9

Using R,

a) Calculate MSB for the data. What type of variability is measured by this quantity? How many degrees of freedom are associated with this quantity? b) Calculate MSw for the data. What type of variability is measured by this quantity? How many degrees of freedom are associated with this quantity?
