Type GRNLAWS in Row: and YEAR in Column: then Run the table. a) Use StatCrunch and the 2006 data to create a 90% condence interval for the the proportion of all Americans answering 'denitely should be' to this question. Include a check of the necessary conditions in your answer. Copy and paste the output from StatCrunch. b) Interpret your interval in context. c} Can you conclude whether a majority of the population would answer 'definitely should be\"? Explain using your condence interval. d) Is there a difference in the responses from 1096 and 2006? Use the segmented bar graphs to comment. 2. The Fair Labor Standards Act was passed in 1938.
