Q2.      In the July 29, 2001, issue of the Journal News (Hamilton, Ohio), Lynn Elber of the Associate Press reported that “while 40 percent of American families own a television set with a V-chip installed to block designated programs with violence, only 17 percent of those patents use the device.

(a) use the report’s results to find an estimate of the probability that a randomly selected American family has used a V-chip to block programs containing violence.

(b) according to the report, more than 50 percent of parents used the TV rating system (TV-14, etc.) to control their children’s TV viewing. How does this compare to the percentage using the V-chip?
