Question

A researcher is interested in the differences between the rates of support for inner city development in Melbourne and Sydney. Data is collected and is reported in the following table.

City	Melbourne	Sydney	Total
Support	85	102	187
Do not support	142	118	260
Total	227	220	447

At a 0.05 level of significance, is there evidence of a significant difference between Melbourne and Sydney rates of support for inner city development?

Using a chi-squared test for differences between proportions state the hypotheses that you are testing, determine the critical value of the chi-squared statistic and state the decision rule.
