Two Microprocessors Are Compared on a Sample of 6 Benchmark

question 6

Multiple Choice

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) \(( - 2.63,0.96 )\)
