Construct a confidence interval for µd, the mean of the differences d for the population of paired data. Assume that the population of paired differences is normally distributed.
-Using the sample paired data below, construct a 90% confidence interval for the population mean of all differences x - y. $$\begin{array} { c | c c c c c }
\mathrm { x } & 6.0 & 4.5 & 4.8 & 2.5 & 6.3 \
\hline \mathrm { y } & 5.7 & 3.3 & 4.4 & 3.2 & 4.0
\end{array}$$
A) $- 0.37
