Mathematical content area: Uncertainty and data
Context: Societal
Process: Interpret
Full Credit Code 11: A response that says that Kevin needed to take into account the actual
number of households with TVs for the two countries.
[Accept “population” as a substitute for “households’] .
•
He is wrong because there are over 22 million more households that own TVs in
France.
•
Because the population of France is about 10 times more than Norway.
•
Because France has more people, the number of people that have a TV is much
larger, so the number of cable TV subscriptions is larger.
Code 12: A response that is based on calculation of the actual number of
subscribers in the two countries.
•
Because France has (24.5 × 0.154) = approximately 3.7 million households that
subscribe to cable TV, while Norway has (2.0 × 0.427) which is approximately
0.8 million households. France has more cable television subscribers.
