The following data represent the muzzle velocity (in feet per second) of rounds fired from a 155-mm gun. For each round, two measurements of the velocity were recorded using two different measuring devices, resulting in the following data. Complete parts (a) through (d) below. Observation 1 2 3 4 5 6 793.3 792.8 794.8 790.1 793.1 792.3 797.6 791.5 802.6 788.3 802.5 791.2 Click the icon to view the table of critical t-values. A B a) Why are these matched-pairs data? OA. The same round was fired in every trial. B. Two measurements (A and B) are taken on the same round. OC. All the measurements came from rounds fired from the same gun. OD. The measurements (A and B) are taken by the same instrument.
