(ii) Largest sample variance (to one decimal place): Smallest sample variance (to one decimal place): Ratio of largest to smallest (to one decimal place): The ratio of the largest to the smallest sample variance is less-than-or-equal-to-four so it is safe to assume that the population variances are approx equal.

This question is about the second part of Step 4 of the six-step One-way Anova F-test procedure
that was taught in this class. Fill in the blanks appropriately.
(ii) Largest sample variance (to one decimal place):
Smallest sample variance (to one decimal place):
Ratio of largest to smallest (to one decimal place):
The ratio of the largest to the smallest sample variance is less-than-or-equal-to-four so it is safe to
assume that the population variances are approx equal.
