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 (122°F) and rate how uncomfortable it was. Given the following data;
Find the estimated error of the mean only.

For counting Money: n1=10, M1=488, SS1=488

For counting Paper: n2 =10, M2=60, SS2=208

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