Sample Exam Question

When you are dealing with small sample sizes what table do you use and what are the 4 steps in using it?

  1. You would use a t-table. The four steps are:
    1) choose confidence level (90%, 95%....)
    2) calculate the degrees of freedom (n-1)
    3) find the value on the table that corresponds with the d.o.f and confidence level.
    4) use the t value for confidence interval.
