1. Americans were asked: Is it the government's responsibility to impose strict laws to make industry do less damage to the environment? Results from both 1996 and 2006 can be found in the GSS. Type GRNLAWS in Row: and YEAR in Column: then Run the table. a) Use StatCrunch and the 2006 data to create a 90% confidence interval for the true proportion of all Americans answering 'definitely should be' to this question. Include a check of the necessary conditions in your answer. Copy and paste the output from StatCrunch. Interpret your interval in context. b) c) Can you conclude whether a majority of the population would answer 'definitely should be'? Explain using your confidence interval. d) Is there a difference in the responses from 1996 and 2006? Use the segmented bar graphs to comment.
