Q1) Recent Gallup poll consisted of 1012 randomly chosen adults who were asked whether "cloning of humans should or must not be allowed."  Results illustrated that 89% of those surveyed indicated that cloning must not be allowed.  A news reporter wishes to find out whether these survey results constitute strong evidence that majority (more than 50%) of people are opposed to such cloning.

a) Suppose that 50% of all people are opposed, evaluate probability of getting at least 89% opposed in survey of 1012 randomly selected people.

b) Based on result in a), is there strong evidence supporting claim that majority is opposed to such cloning?
