The mean is found by dividing the sum of the scores by the number of scores. \r
\n" ); document.write( "\n" ); document.write( "You have two of these values for the 16 students with a mean of 91.5. Use these two values and the formula for the mean to find the sum of the 16 scores.
\n" ); document.write( "Now add the final score to that sum and recalculate the new mean (average) for the 17 students.
