A study was conducted to test if a new drug was effective in reducing the number of headaches. Two groups were formed from a sample with a history of chronice headaches. One group was given the new drug and the other was given a placebo. Of the 30 people that were given the new drug, 20 of them reported relief from their headache. Of the 50 people given the placebo, 25 of them reported relief from their headache. Calculate a 95% confidence interval for the difference in the proportion of subjects reporting relief from their headaches between the new drug and placebo groups.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
