1. The table below presents data collected to determine the relationship between the number of times employees go on official leave and the number of years spent at the firm. The assumption is that years spent at work influences the number of times an individual employee goes on leave.

Years at work	Number of times employee went on leave
2	1
8	3
27	9
15	10
9	5
12	6

1. Determine the linear regression equation for predicting the number of times employees can be expected to go on official leave in this firm.
2. Using the equation in part (a), predict the number of times an employee will go on leave if they worked for 17 years. What if they worked for 30 years?
3. Determine the correlation coefficient and interpret it.

Determine the coefficient of determination ( R2) and explain what it means.
