Part 3 of 8
Points: 0 of 1
Assume that the differences for the given data are normally distributed. Complete parts (a) through (d).
Click here to view the sample data. Click here to view the table of critical \( t \)-values.
(a) Determine \( d_{i}=X_{i}-Y_{i} \) for each pair of data.
\begin{tabular}{|l|c|c|c|c|c|c|c|}
\hline Observation & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\
\hline \( \mathbf{d}_{\mathbf{i}} \) & -0.4 & 0.9 & -3.3 & -3.6 & 0.4 & -2.3 & -2.8 \\
\hline
\end{tabular}
(Type integers or decimals. Do not round.)
(b) Compute \( \bar{d} \) and \( \mathrm{s}_{\mathrm{d}} \).
\( \overline{\mathrm{d}}=-1.586 \) (Round to three decimal places as needed.)
\( \mathrm{s}_{\mathrm{d}}=\square \) (Round to three decimal places as needed.)
