The annual Salary of an electrical engineer is given in terms of the years of experience by the table below. Find the equation of linear regression for the above data and obtain the expected salary for an engineer with 15 years of experience. Round to the nearest $100.
x (years of experience)= 3,5,9,14,18,22,26,33,36
y (salaries in 1000) = 53,56.3,60,64,70,73,76,82
