Fast computer: Two microprocessors are compared on a sample of 6 benchmark codes to determine whether there is a difference in speed the times seconds) used by each processor on each code are as follows: Code 1 2 3 4 5 6 Processor A 26.4 16.5 28.0 15.2 24.0 26.4 Processor B 27.7 18.5 21.8 22.3 27.0 22.3 Send data to Excel Part: 0 / 2 Part 1 of 2 (a) Find a 99.8% confidence interval for the difference between the mean speeds. Let d represent the speed of processor A minus the speed of processor B. Use tables to find the critical value. Carry your intermediate computations to at least 3 decimal places. Round your final answers to 2 decimal places. A 99.8% confidence interval for the difference between the mean speeds is
