A national survey by Ipsos Reid for the Canadian Newspaper Association reveals some interesting statistics about newspaper advertising reading habits of Canadians. Sixty-six percent of Canadians say that they enjoy reading the page advertising and the product inserts that come with a newspaper. The percentage is higher for women (70%) than men (62%), but 73% of households with children enjoy doing so. While the percentage of those over 55 years of age who enjoy reading such ads is 71%, the percentage is only 55% for those in the 18- to 34-year-old category. These percentages decrease with increases in education, as revealed by the fact that while 70% of those with a high school education enjoy reading such ads, only 55% of those having a university degree do so. Canadians living in the Atlantic region lead the country in this regard with 74%, in contrast to those living in British Columbia (63%) and Quebec (62%).

These facts can be converted to probabilities: The marginal probability that a Canadian enjoys reading such ads is .66. Many of the other statistics represent conditional probabilities. For example, the probability that a Canadian enjoys such ads, given that the Canadian is a woman is .70; and the probability that a Canadian enjoys such ads, given that the Canadian has a college degree is .55. About 13% of the Canadian population resides in British Columbia. From this and from the conditional probability that a Canadian enjoys such ads, given that they live in British Columbia (.63), one can compute the joint probability that a randomly selected Canadian enjoys such ads, and lives in British Columbia (.13)(.63) = .0819 . That is, 8.19% of all Canadians live in British Columbia and enjoy such ads.

 

1)What might be some factors that contribute to fact that about 10% more Canadians in the Atlantic region than in other regions of the country enjoy reading newspaper ads?
