Question 3:
A biotechnology firm is planning its investment strategy for research into human cloning. A poll found that only 8% of a random sample of 1012 Canadian adults approved of attempts to clone a human.
a) Find the margin of error for this poll if we want 95% confidence in our estimate of the percentage of Canadian adults who approve of cloning humans.
b) Explain what that margin of error means.
c) If we only need to be 90% confident, will the margin of error be larger or smaller? Explain.
d) Find that margin of error.
