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 persons in each year.)

Formulate the null and alternative hypotheses in terms of a box model.

Do you need one box or two? Why? [ Select ] ["Two boxes because we are comparing two different populations.", "One box because we are interested in the same parameter from each year."]

How many tickets go into each box? [ Select ] ["Both boxes have tickets for each person in the population marked 1 for those who rate clergymen "very high or high" and 0 otherwise.", "The box has tickets for each person in the population marked 1 for those who rate clergymen "very high or high" and 0 otherwise.", "The box has tickets for each person in the sample marked 60% and 54%."]

How many draws? [ Select ] ["The box has 1,000 draws.", "The box has 2,000 draws.", "Both boxes have 1,000 draws."]

What do the null and alternative hypotheses say about the box(es)? [ Select ] ["Null: the percent of 1's in the box is 60%. Alternative: the percent of 1's in the box is less than 60%.", "Null: the percent of 1's in the 2005 box is the same as in the 2000 box. Alternative: the percent of 1's in the 2005 box is smaller than the percent of 1's in the 2000 box.", "Null: the percent of 1's in the 2005 box is smaller than in the 2000 box. Alternative: the percent of 1's in the 2005 box is the same as the percent of 1's in the 2000 box."]
