![s. The camp wants to make sure that the average fun score
does not depend on which activity is the camper's
favorite (boating, crafting, or nature hikes). You decide
to determine if mean fun score is different for the
different activities. Which test procedure you should
use?
A. Simple linear regression
B. Multiple linear regression
C. Two-sample t-test
D. One-way ANOVA
Answer:
6. You want to test if the average fun score for campers who
prefer boating and camping is higher than the fun score
for campers who prefer nature hikes. Give the
hypotheses for this contrast test.
A. Ho: Hpoating ampin Hhikes Vs Ha: (Hosting Hamping ) >nikes
B Ho: 1/2(Houting +Hcamping) = Hnkes vs Ha: 1/2(uoning +Hcanping) < Hnkes
