Problem
Continue with the data presented in Problem Repeat parts 3, 4, and using Satterthwaite' $ formula for the degrees of freedom from which the critical value of the Student's t distribution is derived.
3. Using 0.05, calculate the critical value tc which defines the boundary of the region for which Ho would be rejected. Satterthwaite' s formula for the degrees of freedom. Using 0.05 and the test statistic calculated in part (2), what conclusion do you reach? Interpret your answer Estimate the value of (p1 02) with 95% confidence interval.
