Question: Suppose that a random sample of n= 101 was selected from the employee data. The data are consistent with summary information on salary, and salary begin in each of four years. Carry out an ANOVA to determine whether there is evidence to support the claim that the mean salary, and the mean of begin salaryfor each year was not the same for each of the four years considered.
a) Test at the 0.05 level and at the 0.01 level. The data set is named "Employee Data".
b) Does the salary begin depends on the pre-experience or does the pre-experience depends on the salary begin? Do you expect a positive or negative relationship between these two variables? ( Do the regression)
c) Find the least squares regression line by choosing appropriate dependent and independent variables based on your answer in part a.
