The accompanying data on degree of spirituality for a sample of natural scientists and a sample of social scientists working at
research universities appeared in a paper. Assume that it is reasonable to regard these two samples as representative of
natural and social scientists at research universities. Is there evidence that the spirituality category proportions are not the
same for natural and social scientists? Test the relevant hypotheses using a significance level of 0.01.
