I assume the populations of each community are 'large' ....

Two communities were surveyed in NS for Sunday shopping. In community A, 80% of the residents were in favour and in another community (community B) 65% were in favour of permitting Sunday shopping hours. What is the probability of getting a difference in proportions between community A and B of greater than 20%? (use alpha = 0.05).
I've never seen anything like this before... help?! Thanks!
