In an experiment, a group of college students was told that they were participating in a manual skill study. Half of the students were given a stack of money to count and the other half got a stack of blank pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122F) and rate how uncomfortable it was. Given the following data; Find the estimated error of the mean only.

For counting Money: n1=10, M1=271, SS1=271

For counting Paper: n2 =10, M2=60, SS2=438

Please type the estimated error of the mean only in nearest hundredths place.
