Answer 2

Yes, the 2011 proportion of neuroinvasive West Nile virus cases is more than the 2010 proportion of neuroinvasive West Nile virus cases.

Explanation:

2010 proportion:

629 cases out of 1021. So the proportion is:

`p = (629)/(1021) = 0.616`

2011 proportion:

486 cases out of 712. So the proportion is:

`p = (486)/(712) = 0.683`

0.683 > 0.616 so the 2011 proportion of neuroinvasive West Nile virus cases is more than the 2010 proportion of neuroinvasive West Nile virus cases.
