Research poll, Engineering Mathematics

Assignment Help:

A Pew Research poll was conducted to investigate opinions about global warming.  The respondents who answered yes when asked if there is solid evidence that the earth is getting warmer were then asked to select a cause of global warming.  The results for two age brackets are given in the table.  Use a 0.01 significance level to test the claim that the age bracket is independent of the choice for the cause of global warming.  Do respondents from both age brackets appear to agree, or is there a substantial difference?
