Can someone please help me with question c? Would be really appreciated :)<br> (Picture is attached)
Romashka [77]

Answer:

approx. 1,680,185

Step-by-step explanation:

Out of the 6,547,000 people who they surveyed in 1998, 6.5% of the Canadians(combining the 1.9 and 4.6 percent of males and females who voted for basketball) chose basketball. Assuming the same percentage of people favors basketball in 2004, then you'd simply need to find 6.5% of the population of 2004(which, as given, is 25,849,000), and 1,680,185 is 6.5% of the population.
