Explanation Given: Use for the data of “The average amount of student loan debt” from Internet or library. Formula used: Calculation: Consider the Data from Federal Reserve Bank of New York. The average amount of student loan debt form the year 2004 to 2016 are as: $ 346 , $ 479 , $ 633 , $ 803 , $ 959 , $ 1154 and $ 1480 (in billions) to the corresponding years 2004 , 2006 , 2008 , 2010 , 2012 , 2014 and 2016 . Thus, the representation of given information as: year Loan Debt ( $in billions ) 2004 346 2006 479 2008 633 2010 803 2012 959 2014 1154 2016 1480 The representation of above data in co-ordinate form as ( 2004 , 346 ) , ( 2006 , 479 ) , ( 2008 , 633 ) , ( 2010 , 803 ) , ( 2012 , 959 ) , ( 2014 , 1154 ) and ( 2016 , 1480 ) . The scatter diagram of above data is calculated from TI-83 calculator. The steps are as follows, Step 1: To press the “ON” button. Step 2: Press “STAT” button and choose “Edit”. Step 3: Put L1 ( 1 ) = 2004 , then press “ENTER” for L1 ( 2 ) = 2006 , L1 ( 3 ) = 2008 , L1 ( 4 ) = 2010 , L1 ( 5 ) = 2012 , L1 ( 6 ) = 2014 , L1 ( 7 ) = 2016 . Step 4: Use the arrow key to move between columns for L2 ( 1 ) = 346 , then press “ENTER” for L2 ( 2 ) = 479 , L2 ( 3 ) = 633 , L2 ( 4 ) = 803 , L2 ( 5 ) = 959 , L2 ( 6 ) = 1154 and L2 ( 7 ) = 1480 . Step 5: Press “STAT” key, then select “CALC” than scroll down to “LinReg ( a x + b ) ”. Step 6: Press “ENTER” key, you have a clear screen that sys only LinReg ( a x + b ) . Step 7: Press “ 2 nd ” button then press “ L1 ” key, then press “,” key, again press “ 2 nd ” button then press “ L2 ” key Step 8: Press “ENTER” key After pressing “ENTER” key the linear regression line displayed on the screen of TI-83 calculator as, Step 9: Press “STAT” key, then select “CALC” than scroll down to “LinReg ( a x + b ) ”. Step 10: press “ 2 nd ” button then press “ L1 ” key, then press “,” key, again press “ 2 nd ” button then press “ L2 ” key, again press “,” key
