• Two companies, A and B, have recently conducted aggressive advertising campaigns in order to maintain and possibly increase their respective shares of the market for vitamin supplements. Before the advertising campaigns began, the market share of company A was 45%, whereas that of company B was worth 40%. Other competitors accounted for the remaining 15%.To determine whether these market shares changed after the advertising campaigns, a marketing analyst solicited the preferences of a random sample of 200 customers of vitamin supplements. Of the 200 customers, 102 indicated a preference for company As product, 82 preferred company Bs vitamin supplements, and the remaining 16 preferred the products of one of the competitors. Can the analyst infer at the 5% significance level that customer preferences have changed from their levels before the advertising campaigns were launched? Run the appropriate test in SPSS. Copy and paste the relevant output tables and report the results.
