Question
![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.

UU. ine measurements (A and B) are taken by the same instrument.
b) Is there a difference in the measurement of the muzzle velocity between device A and device B at the x = 0.01 level
of significance? Note: A normal probability plot and boxplot of the data indicate that the differences are approximately
normally distributed with no outliers.
Let d =A₁-B₁. Identify the null and alternative hypotheses.
Ho: Hd = 0
H₁: Hd #0
Determine the test statistic for this hypothesis test.
