Assume that in Canada there are 14 million TV households. A popular TV program, Hockey Night in Canada, aired at 6 p.m. and had a rating of 5.7 and a 10 share. At the 6 p.m. airtime, how many TV sets were tuned into this or another program? (Hint: Ratings are based on total households, whereas share is based on just the households that have their TV sets on at a particular time, in this case at 6 p.m. Because the numerator value remains constant in both the calculation of ratings and share values, by simple algebraic manipulation you can determine from the rating information the number of households with their sets on.)
