The myoglobin sequence, with reference number NM_005368 in Gen bank, has the following frequencies of DNA nucleotides: A C G T 237 278 309 242 Do these data provide sufficient evidence, at the 1% level of significance, that the DNA nucleotides have an unequal distribution, that is the DNA nucleotides are not evenly utilised? Clearly state your hypothesis, test statistic and conclusion. Justify your conclusion and choice of test statistic. plzzzzz!!! -- View this message in context: http://www.nabble.com/statistics-tp25530074p25530074.html Sent from the R help mailing list archive at Nabble.com.

This is not a "please solve my homework for me" newsgroup. Hint: You may want to learn about chi-square tests.

btw., even with homework newsgroups it's typically a no-no if you haven't even tried and do not show that you have done anything by yourself. Basically you are saying, I haven't been to class, I did not read the book either, I haven't done and don't know anything; can somebody else do my work for me, please. I don't know if there is any newsgroup that finds this approach acceptable.
