Question

Employees of a building materials chain facing a shutdown were surveyed on a prospective employee ownership plan. Some employees pledged $10,000 to this plan, putting up $800 immediately, while others indicated that they did not intend to pledge. Of a random sample of 175 people who had pledged, 78 had already been laid off, whereas 208 of a random sample of 604 people who had not pledged had already been laid off. Test, at the 5% level against a two-sided alternative, the null hypothesis that the population proportions already laid off were the same for people who pledged as for those who did not.
