This one is a little tricky and I would love some help with this one.

Given the design of the study and the question of interest, which of the following 4 computer outputs is relevant to use? Paired T-Test and Cl: before shipping, after shipping Paired '1' for before shipping - after shipping N Mean Senev 31: Mean before shipping 5 45.200 0 4. 2071 1. 3315 after shipping 5 41.000 0 5 . 3335 2. 33?5 Difference 5 4.20000 3. 70135 1.55529 95% lower bound for mean difference: 0.67117 T-Test. of mean difference = 0 [vs 3: 0): T-Velue = 2.54 P-Value = 0.032 Two-Sample T-Test and Cl: before shipping. after shipping Two-sample T for before shipping vs after shipping 11 Mean StDev SE Mean before shipping 5 45.20 4.21 1.9 after shipping 5 41.00 5.34 2.4 Difference - nu [before shipping] - nu (after shipping] Estimate for. difference: 4.20000 95% lower bound for difference: -1.55902 TTesi: of difference - 0 (vs )1: TValue - 1.33 PVelue - 0.105 Paired T-Test and Cl: before shipping. after shipping Paired T for before shipping after shipping 13 Heen StDev SE Mean before Shipping 5 45.2000 4.2021 1. 33.15 after shipping 5 41.0000 5.3335 2. 3375 Difference 5 4.20000 3.70135 1.65529 95': upper bound for mean difference: 7.12333 TTest of mean difference - 0 [vs 4: 0): T-Value - 2.54 P-Value - 0.963 Two-Sample T-Test and Cl: before shipping, after shipping mo-senple T for before shipping vs efcer shipping 11 Mean StDev 3E Mean before shipping 5 45.20 4.21 1.9 after shipping 5 41.00 5.34 2. 4 Difference = nu [before shipping} - mu [after shipping} Estimate for difference: 4.20000 95% upper bound for difference: 9.95902 T-Tesi: of difference = 0 (vs (1: T-anue = 1.33 P-Value = 0.395 Grain is fortied with vitamins at the factory when processed. But, before the product reaches the consumer, some of the vitamins may degrade due to time, heat during storage, etc. Suppose the vitamin contents (in milligrams per pound) of ve bags of grain are measured at the factory before shipping, and then again at the retail store after shipping. The results are as shown: Vitamin content Vitamin content Bag before shipping aex shipping 1 45 38 2 47 45 3 48 48 4 38 35 5 48 39
