The plot in the previous exercise seems to indicate that bank size does influence the relationship between wages and length of service. Do separate regressions of wages on length of service for large banks (n= 34) and for small banks (n= 25).

Give the equation of the regression line of wages on length of service for large banks.

Give your answers as presented by Minitab.

The intercept of the regression line is(give your answer to 1 decimal places):

The slope of the regression line is (give your answer to 3 decimal places):
