Question
Given two dependent random samples with the following results:

\[
\begin{array}{|c|cccccccc|}
\hline
\text{Population 1} & 44 & 21 & 39 & 33 & 17 & 31 & 24 \\
\text{Population 2} & 31 & 19 & 36 & 41 & 31 & 21 & 29 \\
\hline
\end{array}
\]

Use this data to find the 80% confidence interval for the true difference between the population means.

Let \( d = \text{(Population 1 entry)} - \text{(Population 2 entry)} \). Assume that both populations are normally distributed.

**Step 1 of 4**: Find the mean of the paired differences, \( \bar{d} \). Round your answer to one decimal place.
