We can conclude that the mean difference between the number of racial slurs that poor and wealthy people make is between 0.3 and 3.7. Note: To calculate the degrees of freedom, we can take the smaller of the two numbers n1 - 1 and n2 - 1. So in the prior example, a better estimate would use 49 degrees of freedom. The t-table gives a value of 2.014 for the t.95 value and the margin of error is. E = tcs = (2.014)(0.85) = 1.7119.
