Question:

Repeat Problem 11, skipping part (e), but use LN_BLDTL as the dependent variable.
Problem 11
a. Conduct a one-way ANOVA, with dosage level (PPM_TOLU) as a categorical predictor.
b. Using the Bonferroni technique, compute all pairwise comparisons.
c. Repeat part (b) using the Tukey-Kramer method.
d. Repeat part (b) using Scheffe's method.
e. The ANOVA overall test corresponds to fitting a polynomial model of order k. What is k?
f. Examine the ANOVA assumptions by computing the estimates of the within-cell variances. Provide frequency histograms for each cell to aid in this examination.
