The following data represent the muzzle velocity (in foot per second) of rounds fined from a 15 Incomplete tach round, two measurements of the velocity worp recorded using two different measuring devices, resulting in the following data. Complete parts (a) Brough [d) below. Observation 1 2 3 4 5 6 5 7939 793.1 790.6 TO14 791.7 7915 800.7 7930 7:57 7905 7952 780.1 (a) Why are those matched-pairs data? O A. The same round was fired in every trial O B. The measurements (A and B) are taken by the same instrument. O C. All the measurements came from sounds fired from the same gun. O D. Two measurements (A and () are taken on the same round. (b) Is there a diference in the measurement of the muzzle velocity between device A and device B at the i = 0.01 krvol of significance?
