\n" ); document.write( "\n" ); document.write( "It is impossible to tell the range of a set of data if you only know the average. The only thing that you know for certain, given that the average was 65 is that the total of all the scores is 29 times 65, but there is a myriad of ways that 29 scores that individually have a maximum of 100 and a minimum of 0 can add up to 1,885.\r

\n" ); document.write( "\n" ); document.write( "Since you know that your score is 57, then you can say with certainty that the lowest score in the class is in the closed interval [0, 57]. That is specific as you can possibly get with the information given.\r
