A quality control engineer studied the relationship between years of experience as

a system control engineer and the capacity of the engineer to complete within a given time a

complex control design including the debugging of all computer programs and control devices.

A group of 25 engineers having widely differing amounts of experience (measured in months of

experience) was given the same control design project. The results of the study are given in the

following table with y= 1 if the project was successfully completed in the allocated time and

y=0 if the project was not successfully completed.
