A marketing research analyst collects data for a random sample of 100 customers out of the 4,000 who purchased a particular “coupon special.” The 100 people spent an average of X = $24:57 in the store with a standard deviation of s = $6:60. Before seeing these sample results, the marketing manager had claimed that the average purchase by those responding to the coupon offer would be at least $25.00. Can this claim be rejected, using the 5 percent level of significance?
