Fast computer: 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 as follows: Processor A 27.8 Processor B 25.8 Send data to Excel Part: 0/2 Part 1 of 2 Code 17.3 23.8 15.0 27.4 23.4 17.6 23.5 14.2 26.8 21.5 (a) Find a 90% confidence interval for the difference between the mean speeds. Let d represent the speed of the processor A minus the speed of processor B. Use the TI-84 calculator. Round the answers to two decimal places. A 90% confidence interval for the difference between the mean speeds is
