So what we have here is the source of variation, the sum of squares, the degrees of freedom, then we need to find what is the sum of, mean sum of squares, and the value of the test statistic and the p -value.
00:16
So this is the complete table.
00:19
This sum of squares is the treatment, could be the error or the total, and they are saying that the sum here is 180.
00:27
For the total we have 480, and the degrees of freedom is 3, for the error is 16, and for the total is 19.
00:37
So in letter a we should find the number of treatments.
00:40
So the number of treatments that we have is, because the degrees of freedom is the number of treatments, minus 1, this means that the number of treatments will be the degrees of freedom for the treatment plus 1, so we have 4.
00:54
Then for letter b we should find what is the mean square for the treatment, which is given by the sum of squares for the treatment divided by the degrees of freedom for the treatment...
