📌Module-5: Design of Experiments & ANOVA
📝 Question No.: 10(b)
📝 Topic: Two Way ANOVA with replications


📌 Exact Question :
Set up ANOVA table for the following information relating to three drugs
testing to judge the effectiveness in reducing blood pressure for three
different groups of people.

Group of people Drug
X Y Z
A 14 10 11
15 9 11
B 12 7 10
11 8 11
C 10 11 8
11 11 7

Do the drugs act differently?
Are the different groups of people affected differently?
Is the interaction term significant?

Answer the above questions taking a significant level of 5%.
Given F(2, 9) = 4.26, F(4, 9) = 3.63.
