i.) An introductory stats professor hypothesizes that 50% of students learn best by watching the videos, 10% by reading the book, 20% by solving questions, and the rest from the discussion forums.

F-test c. hypothesis test for a single mean d. X^2 test of goodness of fit e. ANOVA f. X^2 test of independence g. Z-test ii.) True or false: The χ2 statistic is always non-negative.
