Question

Growth (12,10,8,11,6,7,2,3,3)
Tannin (0,1,2,3,4,5,6,7,8)

e.g tannin at 0 growth at 12, tannin at 8 growth at 3

It contains two variables tannin and growth. Tannin is an inhibitor of fungi growth. In an experiment a researcher measured the amount of growth of fungi at different concentrations of tannin (between 0 to 9 mmol/l). Growth was measurred as the amount of area occupied from the fungi after 1 day of exposure.

Q. What is the value for the mean sum of squares of the residuals? (round to 3 decimal places x.xxx)

Explanation / Answer

Here tannin is an independent varivle and growth is an dependent variable depndint upom the value of tannin hence we run an regression analysis in excel to find the man sum os square df SS MS F Significance F Regression 1 88.81667 88.81667 30.97398284 0.000846074 Residual 7 20.07222 2.86746 Total 8 108.8889 From above table we can see that mean sum sqaure for residual is 2.86746
