a.) From the scatter plot shown, it can be seen that the points are relatively distributed in a way as such that as the salary increases, the employee satisfaction score increases.
Therefore, the there is a positive relationship between salary and employee satisfaction scores.
b.) Given that the model s modelled by the function y = 0.0005x + 60
where: y is the employee satisfaction score and x is the salary.
Therefore, the predicted employee satisfaction score based on the model for a salary of $65,000 is y = 0.0005(65,000) + 60 = 32.5 + 60 = 92.5
c.) The number 0.0005 in the model unctiom represents the amount of increase in the employee satisfaction score for every $1 increase in salary.
