In July 29 2002, the gallup organization issue of the Journal News (H Ohio) Lynn Elber of the Associated Press reported on a study conducted y the Kaiser Family Foundation regarding parents use of television set V-chips for controlling their children's TV viewing. The study asked parents who own TV's equipped with V chips whether they used the devices to block programs with objectionable contentment.
Suppose we wish to used the study results to justify the claim that fewer than 20 % of parents who own TV sets with V-chips use the devices. The study actually found that 17% of the parents polled used the v -chips ,if the poll surveyed 1,000 parents and if for the sake of the argument we assume that 20 percent of the parents who own v-chips actually use the devices (that p=2)
Calculate the probability of observing a sample proportion of .17 or less.
