Expression levels of GeneA and GeneB were measured in 10 cell lines. The researcher would like to know if expression levels of GeneA and GeneB are related. a. Use a parametric method to test if GeneA and GeneB are correlated. b. Use a non-parametric method to test if GeneA and GeneB are correlated. c. Researcher hypotheses that level of GeneB is a linear function of Gene A, test if such a linear relationship is significant or not. Carry out all above tests for a = 0.05.
