Question
Transcribed Image Text:b) Run an ANOVA test using the statistical software package of your choice to
compare solvability of solvents before adding solution "X".
Note: create a subset of the data to separate "with additive x" and "without additive
x", to allow analysis of just one group.
c) Check whether the assumptions of normality and variance equality are satisfied for
part b of this question.
Use a nonparametric test and compare your finding with that from part b.
Use the residuals from
the ANOVA test and include Q-Q plot and Boxplot.
d) Perform a natural log (logarithm base e) transformation of the solvability
data and run the ANOVA test
once again for the same investigation as in parts b and c of this question.
Have the results changed in any way?
