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 Test statistics for two independent samples. For counting Money: n1=10, M1=50, SS1=2300 For counting Paper: n2 =10, M2=60, SS2=2382

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
