1. Suppose interest lies in estimating the proportion of people in Harvard who believe climate change is a serious problem for current and future generations. In addressing this question, a student who has taken BIO123 obtains a large representative sample of 1000 where 58.5% of the subjects stated that climate change is a serious problem. Skeptics believe that the sample proportion reported by the student is inflated, and claim that the true proportion of people who believe climate change is a serious problem is 50% or less.

For the context described above, the parameter of interest is:

a) the proportion of people in Waterloo who believe climate change is a serious problem for current and future generations.

b) the mean age of the people in Waterloo who believe climate change is a serious problem for current and future generations.

c) the mean age of the people in Waterloo who do not believe climate change is a serious problem for current and future generations.

d) climate change.
