representative sample? comparison of variance?

#1
Hello. i did an online survey. i was able to classify the responses by the districts they came from. I also obtained the total population for each district. i would like to know if my sample is representative. i used a f-ratio comparison of variance. is that the correct test? if no please tell me what test to use and how to do it. I am very very inexperienced at statistics. thank you so much.

please see attached document for the data. the left column is the percentage of the population in each district. the right column is the percentage of the sample responses from each district.
