ANOVA Home Task - 2

Suppose we want to test the hypothesis that “smoking causes lung cancer”. Following is the expression levels of AGER gene (a biomarker of lung cancer) recorded in three samples:

Chain smoker

Non smoker

Passive smoker

3.2

4.8

5.3

2.1

3.1

6.1

0.8

4.0

6.9


  Apply the appropriate ANOVA test to   check if expression of AGER is   significantly different among these three   samples.
