Adverse reactions to a certain drug have been studied in clinical trials, and the table below summarizes results for digestive system effects among patients from different treatment groups Use a 0.01 significance level to test the claim that experiencing an adverse reaction in the digestive system is independent of the treatment group. Does treatment with this drug appear to have an effect on the digestive system? There is evidence to warrant rejection of the claim that experiencing an adverse reaction in the digestive system is independent of the treatment group It appears that treatments with the drug are associated with in adverse effects on the digestive system.

Explanation / Answer

H0: The adverse reaction is independent of the tretment group

H1:The adverse reaction is not independent of the tretment group

alpha:1%

Test statistic:

Chisquare=17.6625

P value= 0.000146

Hence P<0.01, we reject the H0. Hence there is sufficient evidence to reject the claim.

Hence the adverse reaction is not independent of the tretment group
