From today's NYT:
On Basic Religion Test, Many Doth Not Pass
Excerpt:
Americans are by all measures a deeply religious people, but they are also deeply ignorant about religion.

On average, people who took the survey answered half the questions incorrectly, and many flubbed even questions about their own faith.
Those who scored the highest were atheists and agnostics, as well as two religious minorities: Jews and Mormons.

Appendix B: Survey Topline
If Mignat is still around he might want to take a look at this to see how real surveys are conducted and how their results are presented and summarized.
