Calculate the ANOVA table for and carry out the F test.

 

(Computer exercise) Refer to the snap-bean data of Exercise 11.S.5.Apply a reciprocal transformation to the data.That is, for each yield value Y,calculate .

(a) Calculate the ANOVA table for and carry out the F test.

(b) It often happens that the SDs are more nearly equal for transformed data than for the original data. Is

this true for the snap-bean data when a reciprocal transformation is used?

(c) Make a normal probability plot of the residuals,  . Does this plot support the condition that

the populations are normal?

Exercise 11.S.5:

In a study of the mutual effects of the air pollutants ozone and sulfur dioxide, Blue Lake snap beans

were grown in open-top field chambers. Some chambers were fumigated repeatedly with sulfur dioxide. The air

in some chambers was carbon filtered to remove ambient ozone. There were three chambers per treatment

combination, allocated at random. After one month of treatment, total yield (kg) of bean pods was recorded

for each chamber, with results shown in the accompanying table.34 For these data SS(between) = 1.3538

, and SS(within) = 0.27513. Complete the ANOVA table and carry out the F test at ∝= 0.05.

Prepare an interaction graph (like Figure 11.7.3).
