The mean for a set of 28 scores is 80. Suppose two more students take the test and score 60 and 50. What is the new mean?

document.write( "When there are 28 students,\r\n" );
document.write( "\r\n" );

document.write( "Now after those two extra students take the test,\r\n" );
document.write( "the new sum of scores will be 2240 + 60 + 50 = 2350,\r\n" );
