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
A 794.4 791.1 794.9 790.2 790.1 790.9
B 795.7 786.4 796.6 788.7 798.0 787.1
a. Why are these matched-pairs data?
b. Is there a difference in the measurement of the muzzle velocity between device A and device B at α=0.01
c. Construct a 99% confidence interval about the population mean difference. Compute the difference as device A minus device B. Interpret your results.
