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.
subscript: group.Step-by-step explanation
Step 1.
As the significance level, is given to be and the 
is 
.
Which implies that 
.
Therefore,
At significance level, there is enough evidence that more population is available for in comparison to that of .
Hence, option 
is the correct option.
