A survey of voters conducted one month ago showed a political candidate, Bob, had an approval rating of 8.3 (on a scale from 1 to 10 where 1 represented complete disapproval.) After taking part in several debates with his chief opponent Melanie, another survey of voters was conducted, and the results of the survey are in the data file above. The approval column is the approval rating for Bob as per the voter. Using a baseline mean of 8.3, determine the p-value for a test of whether Bob lost approval rating after the debates. Round to three decimal places.
