(a) Reason why the data is matchedpairs data:
The data shows that the muzzle velocity of rounds fired from 155mm gum and two measurements of the velocity were recorded using two different measuring devices.
From the given information, it is observed that the two measurements of A and B are taken on the same round. Thus, the given data represents the matchedpairs data.
The correct option is B. Two measurements (A and B) are taken on the same round.
(b) Testing whether there is a difference in the measurement of the muzzle velocity between device A and device B:
The hypotheses are given below:
Null hypothesis:
H_{0}: µ_{d} = 0
Alternative hypothesis:
H_{a}: µ_{d} ≠ 0
Test statistic:
Stepbystep procedure to obtain the test statistic and Pvalue using the MINITAB software:
Output using the MINITAB software is given below:
From the MINITAB output, the test statistic is −0.94 and the P value is 0.39.
Decision rule:
If Pvalue ≤ α, reject the null hypothesis.
If Pvalue > α, fail to reject the null hypothesis.
Conclusion:
From the output, it is observed that the Pvalue is 0.39.
Here, Pvalue is greater than the level of significance.
That is, Pvalue (=0.39) > α&n...
