2. A team of eye surgeons has developed a new technique for eye operation to restore the sight of people. Under the old method, it is known that only 30% of the patients who undergo this operation recover their eyesight. Suppose that surgeons have performed n = 225 operations using the new method and that x = 88 have been successful. Can we justify the claim that the population proportion is different from 30% ? Use a a=0.01. (Hint: use the Normal Distribution)
