Question
This is a follow-up question to Question 4(a-c) in Homework 4. You don't have to correctly
answer that question in order to solve this question.
Suppose X1, ... , Xn Bernoulli(p) with unknown p. Consider testing for Ho : p = Po
vs. H1 : p + po for some known quantity po E (0, 1). Based on Question 4(c) in Homework
4, an approximate (1– a) x 100% CI for p (when n is large) is
i.i.d.
Pn+ Za/2\/
Pn(1 – Pn)
Pn (1 – Pn)
, În + %1-a/2\/
where Pn = X, and za is the B-quantile for standard normal. Please construct a hypothesis
test with type I error rate being approximately 0.05 when n is large.
Instruction: In your answer, please specify your test (i.e., when do you reject Ho and
when do you not reject H?), and justify that it indeed has type I error rate 0.05. In your
justification, if you cite a theorem studied in class, please name that theorem or state the
slide number and lecture note number that contains the theorem.
