Drug trials are being done on a new asthma medication. Suppose that in the group recieving the medication 400 of the 600 subjects have improved oxygen levels. In the group recieving the placebo, 360 of the 600 subjects have improved oxygen levels. Does the evidence suggest that a higher proportion of subjects in the group recieving the medication have improved oxygen levels than subjects recieving placebo at a .01 significance level?
