Suppose that you select a random sample of people and ask for their politicalviewpoint and whether or
not they support a particular policy proposal. Supposethat 60% of liberals support the proposal,
compared to 35% of moderates and25% of conservatives. For which sample size will this result provide
strongerevidence that the three political groups do not have the same populationproportions who
support the proposal - (answer)Sample size of 200 for each group
