In an Experiment to Determine Whether There Is a Systematic

question 13

Multiple Choice

In an experiment to determine whether there is a systematic difference between the weights obtained with two different mass balances, six specimens were weighed, in grams, on each balance. The following data were obtained:
$\begin{array}{crr}\hline \text { Specimen } & {\mathrm{A}} & {\mathrm{B}} \\\hline 1 & 7.97 & 7.95 \\2 & 10.27 & 10.25 \\3 & 6.70 & 6.70 \\4 & 10.22 & 10.21 \\5 & 7.89 & 7.88 \\6 & 5.10 & 5.07 \\\hline\end{array}$
State a conclusion using the $\alpha = 0.05$ level of significance.

• A) Reject \(H _ { 0 }\). The mean difference appears to differ from zero.
• B) Do not reject \(H _ { 0 }\). There is insufficient evidence to conclude that the mean difference differs from zero.
