Unformatted text preview: er words, the probability above tcrit and the probability below –tcrit both equal α/2. This probability gives us enough information to determine (using a computer) where tcrit is. p(tdf > tcrit) = α/2 (7) As usual, tdf represents the random variable whose probability distribution is the t distribution with df degrees of freedom. Therefore, Equation 7 says that, according to this distribution, the probability of a result greater than tcrit equals α/2. Formulas for Confidence Intervals. A confidence interval gives the range of values for some population parameter that are consistent with the data. More pr...
