Question 1: paired data Using data in table "T6-1.dat", perform hypothesis testing of paired data of two variables, where Ho: uD= [uD1, uD2 ] = [0 0] Using R programming Compute the following: 1. Mean difference d.bar, 2. Variance covariance matrix Sd, 3. Computed test statistic T2, 4. degrees of freedom df 5. Critical value 6. Decision 7. Simultaneous confidence intervals of d1, d2 using linear combinations 8. Bonferroni's simultaneous confidence intervals of d1, d2 6 27 25 15 6 23 28 13 18 64 36 22 8 44 35 29 11 30 15 15 31 34 75 44 64 28 26 42 30 71 124 54 64 43 54 34 56 3 30 29 29 20 20 14 39 21
