Suppose that 60% of people in the population support raising taxes to pay for wetlands preservation. Suppose you randomly sample 100 people and ask them whether they support raising taxes for this purpose. If you divide the number of people in your sample who support raising taxes by the total number of people asked (100), you obtain a random variable, let’s call it p^(p hat). Use the central limit theorem to come up with the approximate probability that p hat is within 0.1 of the true proportion 0.6.
