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 an each code are as follows: Code 1 2 3 4 5 6 Processor A 22.1 18.5 23.3 16,0 283 222 Processor 25.8 15.3 21.7 23.5 247 24.1 Santa Excel Part: 0/2 Part 1 of 2 (a) Find a 98% confidence interval for the difference between the mean speeds ut represent the speed of the processor Aminus the speed of processor B. Use the T1-84 calculator Round the answers to two decimal places A 98% confidence interval for the difference between the mean speeds
