Identify Null and Alternative Hypotheses Regions for a Two Sample Test

1 point possible (graded)

As above, you are testing for whether a drug is effective using data comprising of yes or no responses from both the treatment and control groups to the question did you recover from the illness at the end of this clinial trial?"

As above, you model

• the treatment group's responses as X1,,XniidBer(pdrug);

• the control group's responses as Y1,,YniidBer(pcontrol).

where Xi=1 means the response is Yes", and Xi=0 mean No", and similarly for Yi. You assume the two sets of responses are independent of one another.

The statistical model for the example in the drug testing is ({0,1}2,{P(pcontrol,pdrug)}(pcontrol,pdrug)(0,1)2).

In the problem above, you formulated the null and alternative hypotheses. Which of the following depicts the regions 0 (corresponding to the null hypothesis) and 1 (corresponding to the alternative hypothesis)?
