The article "Americans Seek Spiritual Guidance on Web" (San Luis Obispo Tribune, October 12, 2002) reported that 68% of the general population belong to a religious community. In a survey on Internet use, 84% of "religion surfers" (defined as those who seek spiritual help online or who have used the web to search for prayer and devotional resources) belong to a religious community. Suppose that this result was based on a sample of 512 religion surfers. Is there convincing evidence that the proportion of religion surfers who belong to a religious community is different from .68, the proportion for the general population?
