Two microprocessors are compared on a sample of 6 benchmark codes to determine whether there is a difference in speed. The times (in seconds) used by each processor on each code are given below:
$\begin{array}{lcccccc}
&{\text { Code }} \
& 1 & 2 & 3 & 4 & 5 & 6 \
\hline \text { Processor A } & 27.1 & 16.1 & 20.5 & 21.4 & 13.6 & 16.3 \
\text { Processor B } & 26.2 & 17.2 & 24.4 & 23.2 & 12.7 & 16.3 \
\hline
\end{array}$
Find the 90% confidence interval for the difference between the mean speeds.
A) $( - 2.51,0.84 )$
B) $( - 2.36,0.69 )$
C) $( - 2.43,0.76 )$
D) $( - 2.63,0.96 )$
