Chapter 11.2, Problem 17Q

To determine

To calculate: The following table shows the percentages of hospitals willing to rehire medical technicians who have been away from that career for x years (154). It can be argued that the fitted line should necessarily have a y-intercept of 100 because no employer would refuse to hire someone (due to outdated skills) whose career had not been interrupted at all – that is, applicants for whom x = 0. Under that assumption, use the result l000t from Question 11.2.16 to fit these data with the model $y=100+bx$.

Year of Inactivity, x	Percent of Hospitals Willing to Hire, y
0.5	100
1.5	94
4	75
8	44
13	28
18	17
