In an Experiment to Determine Whether There Is a Systematic

Multiple Choice

In an experiment to determine whether there is a systematic difference between the weigh obtained with two different mass balances, six specimens were weighed, in grams, on eac balance. The following data were obtained:
$\begin{array}{ccc}\hline \text { Specimen } & \mathrm{A} & \mathrm{B} \\\hline 1 & 14.89 & 14.89 \\2 & 13.06 & 13.07 \\3 & 14.49 & 14.49 \\4 & 13.25 & 13.23 \\5 & 10.18 & 10.14 \\6 & 7.58 & 7.57 \\\hline\end{array}$

State the null and alternate hypotheses.

A) $H _ { 0 } : \mu _ { d } > 0 , H _ { 1 } : \mu _ { d } < 0$
B) $H _ { 0 } : \mu _ { d } = 0 , H _ { 1 } : \mu _ { d } \neq 0$
C) $H _ { 0 } : \mu _ { d } = 0 , H _ { 1 } : \mu _ { d } < 0$
D) $H _ { 0 } : \mu _ { d } = 0 , H _ { 1 } : \mu _ { d } = 0.01$
