I have a population of 11 samples. Can I take the mean from 2 of those 11 samples and use a one sample t test to determine if the mean of the 2 samples differs from the 11 sample population? Is there a better method? Thank you
The 11 were selected based on census criteria and infection rates. The two were then identified for being unique geographical regions (islands). The other 9 are on continents. The question is do the infection rates on the islands differ from the infection rates on the mainland.
