Question:
The Gallup poll asks respondents how they would rate the honesty and ethical standards of
people in different fields--very high, high, average, low, or very low. The percentage who rated
clergy "very high or high" dropped from 60% in 2000 to 54% in 2005. This may have been due
to scandals involving sex abuse; or it may have been a chance variation. (You may assume that
in each year, the results are based on independent simple random samples of 1,000 people in
each year.)
