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    1    2    3    4    5    6    7    8    9    10
Age    30    50    40    55    30    28    60    25    30    45
Sick Days    7    4    3    2    9    10    0    8    5    2

 

The estimated regression equation and the standard error are given.
 

Sick Days=14.310162−0.236900(Age)



Se=1.682207
