Question: You Have Created The Following Design To Compare The Effects Of Two Different Drugs (X1 And X2) To Reduce High Blood Pressure On Three Groups, All Of Which Were Randomly Assigned. Participants’ Blood Pressure Was Measured Before Taking The First Dose (T1), 3 Months After The First Dose (T2) And Again 3 Months Later (T3). T1 T2 T3 Group 1 O1 X1 O2 …

You have created the following design to compare the effects oftwo different drugs (X_{1 and} X₂) to reducehigh blood pressure on three groups, all of which were randomlyassigned. Participants’ blood pressure was measured before takingthe first dose (T1), 3 months after the first dose (T2) and again 3months later (T3).

T1                   T2        T3

Group1          O₁       X₁       O₂       O₃

Group2          O₄       X₂       O₅       O₆

Group3          O₇  O₈       O₉

a) Explain these findings. Draw a conclusion about thedifferent drugs effectiveness on lowering bloodpressure:

O₂ = O₅ = O₈ = O₉> (greater than) O₃ = O₆  

b) Would the conclusions you drew in a change ifO₁, O₄, and O₇ were NOT equal?Explain your answer.
