The art of computer systems performance analysis.

Not necessary, but please show work if you can.

14.3 The memory size of the seven programs mentioned in the disk I/O and CPU time data were also measured. The memory size (in kilobytes) and CPU time (in milliseconds) pairs observed are 1(70, 2), (75, 5), (144, 7, (190, 9), (210, 10), (235, 13), (400, 20). Analyze the data using a simple regression model to predict CPU time as a function of the memory size
