You can put this solution on YOUR website! the mean is 22.1
the standard deviation is 81.7
the sample size is 65.
the standard error is the standard deviation divided by the square root of the sample size = 81.7 / sqrt(65) = 10.13363782 rounded to the number of digits displayed by the calculator i used (ti-84 plus).
