Suppose that in one town 12% of women and 8% of men are vegetarians. Let 1 denote the proportion of vegetarians among a sample of  200 women selected randomly from the town.  Let 2 denote the proportion of vegetarians among a sample of 100 men selected randomly from the town.  What is the distribution of  1 - 2  and what are its mean and standard deviation? Assume that the two samples are independent.
1 - 2 is approximately normally distributed with a mean of 0.04 and a standard deviation of 0.0356.
1 - 2 is exactly normally distributed with a mean of 0.4 and a standard deviation of 0.0356.
1 - 2 is exactly normally distributed with a mean of 0.4 and a standard deviation of 0.00127.
1 - 2 is approximately normally distributed with a mean of 0.04 and a standard deviation of 0.00127.
