	Healthy	Autoimmune	Cancer
Number of People Eaten	59	22	25
	48	23	30
	61	19	29

Conclusion & Interpretation:

Answer 1

Applying ANOVA:

for 0.05 level and (2,6) degree of freedom , critical F =5.143

Conclusion and interpretation: as test statistic 50.475 is higher than critical value, we reject Ho.

There is sufficient evidence at 0.05 level to conclude that there is a preference by the status of health in Zombies.
