A company wants to determine a confidence interval for the average CPU time of their teleprocessing transactions. A sample of 15 random transactions, in seconds, is given below. Assume that the transaction times follow a normal distribution with a standard deviation of 0.5 seconds. Determine a 98% confidence interval for the average CPU time in seconds. Round your answers to two decimal places and use ascending order. Time 6.51 5.1 5.03 5.93 4.84 6.59 5.03 6.69 7.12 5.69 6.25 5.32 4.11 6.28

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
