Question

Quizplus · Accepted Answer

The sample size is sufficiently large (n=500) to make meaningful conclusions about the population. The difference between the current average weight (86 kg) and the average weight 10 years ago (83 kg) suggests that Canadians may be getting heavier. However, further analysis (such as hypothesis testing) would be needed to confirm whether this difference is statistically significant. Therefore, B is the best choice as it acknowledges the potential trend but does not make any definitive conclusions.
