A marketing study had as its purpose the examination and comparison of response rates by different sized business to postal surveys. 200 large and 200 small companies were investigated. A company was deemed to have responded if the survey was returned within 6 weeks of being posted out. The data are shown in the Table. Small Large Total Response 125 96 221 No Response 75 104 179 Total 200 200 400 Chi-Sq = 8.504; DF = 1; P-Value = 0.004 Table. Results of Survey Experiment State the null and alternative hypotheses associated with the chi-squared test. Interpret the result in this case.
