He randomly sampled 300 individuals and asked them how much money they make annually as well as how happy they were at this point in their life on a scale from 1-10. He then proceeded to analyze the data and came up with the following regression equation where X represents the amount of money in tens of thousands of dollars that they made (i.e. $75,000 would correspond to 7.5) and Y represents their predicted happiness level:   Use this linear regression equation to predict the an individuals happiness level if their annual income is $50,000.  Type in your answer as a decimal rounded to 3 decimal places. For example, if you thought the answer was 6.54321 then you would type in 6.543.
