Question:

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 Y" = 1/Y.
(a) Calculate the ANOVA table for Y' 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 quantile plot of the residuals, (y'ij - 'i). Does this plot support the condition that the populations are normal?
