Neuroinvasive West Nile virus is a severe disease that affects a person’s nervous system. It is spread by the Culex species of mosquito. In the United States in 
there were 
reported cases of neuroinvasive West Nile virus out of a total of 
reported cases and there were 
neuroinvasive reported cases out of a total of 
cases reported in 
. Is the proportion of neuroinvasive West Nile virus cases more than the proportion of neuroinvasive West Nile virus cases? Using a 
level of significance, conduct an appropriate hypothesis test.

subscript: group.Step-by-step explanation
Step 1.
As there are two samples are given in the problem, the proportion of neuroinvasive West Nile virus cases and the proportion of neuroinvasive West Nile virus cases.
Therefore, this is a test of two proportions.
Hence, option 
is the correct option.
