A researcher conducts a one-way ANOVA to compare the effectiveness of three different diets (A, B, and C) on weight loss over a period of 12 weeks. The ANOVA results indicate a significant difference in weight loss among the diets. To identify which specific diets differ from each other, the researcher decides to perform a Tukey post hoc test. What is the primary function of the Tukey post hoc test in this context?

A horticulturist is testing three different fertilizer types — FertA, FertB, and FertC — to see if they produce different average plant growth (in centimeters) after six weeks. Twelve plants are randomly assigned to each fertilizer type. Use an appropriate hypothesis test, at the 5% level of significance, to determine whether there are statistically significant differences in mean growth among the three fertilizers. Question of interest: which fertilizer(s) maximize plant growth? The descriptive statistics have been provided:
