Suppose n independent Bernoullipi trials where pi is the probability of success are conducted. Suppose we wish to test the hypotheses
H :pi vs H :pi
and we wish to use X the number of successes obtained in the trials, as a test statistic. Then using binomial tables:
a Explain what would be a reasonable critical region and why?
b If we choose X in X in X in and X in to be four critical regions, find the corresponding probabilities of TypeI error, and comment;
c When the true value of pi ie H is true find the probabilities of TypeII error for the above four critical regions, and comment;
d What are the corresponding values of power for the four critical regions, and what do you observe from them?
