Question
The personnel director of a large hospital is interested in determining the relationship (if any) between an employee’s age and the number of sick days the employee takes per year. The director randomly selects ten employees and records their age and the number of sick days which they took in the previous year.
| Employee | 11 | 22 | 33 | 44 | 55 | 66 | 77 | 88 | 99 | 1010 |
|---|---|---|---|---|---|---|---|---|---|---|
| Age | 3030 | 5050 | 4040 | 5555 | 3030 | 2828 | 6060 | 2525 | 3030 | 4545 |
| Sick Days | 77 | 44 | 33 | 22 | 99 | 1010 | 00 | 88 | 55 | 22 |
The estimated regression line and the standard error are given.
Sick Days=14.310162−0.2369(Age)
se=1.682207�
se=1.682207�
Find the 90% confidence interval for the average number of sick days an employee will take per year, given the employee is 21. Round your answer to two decimal places
