Two measuring devices A and B were used to measure the muzzle velocity(in feet per second) of rounds fired from a 155-mm gun. For each round, 2 measurements of velocity were recorded. The researcher wanted to determine if there is difference in the measurement of the muzzle velocity between device A and device B.

Determine if the sampling isdependent
orindependent.
