The United Way campaign is underway and organizers are concerned that the weak and steadily declining state of the Canadian economy is resulting in lower than average levels of contribution. Historically the inflation-adjusted average contribution to the United Way by full-time employed Kitchener-Waterloo residents has been $240. (a) As a preliminary investigation of the hypothesis that contributions to the United Way are decreasing, the campaign director takes a random sample of fifteen names from the phonebook, screening them first for full-time employment status, and then collects estimates of the amounts each of the fifteen people plan to give to the United Way this year. The following charitable intentions are reported: $210; $0; $60; $1,000; $0; $150; $250; $50; $20; $0; $500; $100; $0; $600; $150. On the basis of these data is the director's prediction likely correct? Use the .05 significance level. Question w What are the null and alternative hypotheses? O HO: l1 = $240; H1: u at 240 0 Ho: u at $240; H1: u = 240 0 Ho: u= $0; H141
