Question about Rank Sum Test

#1
The file CO2.csv contains information about the CO2 uptake of trees in two locations.
The first few lines of the file are
> co2[1:5,]
Type uptake
1 Quebec 16.0
2 Quebec 30.4
3 Quebec 34.8
4 Quebec 37.2
5 Quebec 35.3
>

Perform a nonparametric test to determine if the uptake is the same in Mississippi
and Quebec.What is the p-value of the test?

I am confused as to which test I should use in this situation. I tried wilcox.test(data$uptake~data$Type,exact=FALSE) and got a p-value of 5.759e-08, but I am not sure if this is correct because I thought I should be using a binom.test? Can anybody help me?

I am confused whether to do a sign test by computing the difference (A-B) between the positives, negatives, and ties of the Mississippi and Quebec values and then using a binom.test versus just using a rank sum test for unpaired data. Would they give me the same value? I tried rearranging the values in excel and using a sign test, but I got a different p-value. Thanks for the help.
