With a 05 and a sample of n 15 participants in a repeatedm

With a = .05 and a sample of n = 15 participants in a repeated-measures study comparing two treatments, what are the t statistic boundaries for the two-tailed critical region?

Solution

given a = .05 and a sample of n = 15 participants in a repeated-measures

degrees of freedom = n-1 =14

t statistic boundaries for the two-tailed critical region is (-2.145,2.145)
