7. [-/1 Points] DETAILS ILLOWSKYINTROSTAT1 10.HW.117. MY NOTES A new AIDS prevention drug was tried on a group of 240 HIV positive patients. Forty-nine patients developed AIDS after four years. In a control group of 240 HIV positive patients, 67 developed AIDS after four years.

If the p-value is 0.0275, what is the conclusion (use a = 0.05)? O There is sufficient evidence to conclude that the method reduces the proportion of HIV positive patients who develop AIDS after four years. O The method has no effect.
