Twelve people were interviewed and asked how many years they stayed at their first job. Three people are still employed at their first job and have been there for 1.5. 3.0 and 6.2 years. The others reported the following data for years at first job: 0.4, 0.9, 1.1. 1.9. 2.0, 3.3, 5.3, 5.8. 14.0. Using hand calculations. compute a nori parametric estimator for the distribution of T = time spent (in years) at first job. Verify your hand calculations using MATLAB. According to your estimator, what is the estimated probability that a person stays at their job for less than four years? Construct a 95% confidence interval for this estimate.
