Consider a single observation X from a Cauchy distribution centered

Suppose that we wish to test the hypotheses
H0: θ ‰¤ θ0,
H1: θ >θ0.
Let δc be the test that rejects H0 if X ‰¥ c.
a. Show that π(θ|δc) is an increasing function of θ.
b. Find c to make δc have size 0.05.
c. If X = x is observed, find a formula for the p-value.
