Theory that the slope of the regression line, Basic Statistics

Theory that the slope of the regression line

Consider the following time series data of sales per year:

Year Sales

1995 22.2

1996 23.0

1997 24.4

1998 25.8

1999 27.6

Enter these data in Excel and run the following regression:

Sales = Intercept + Slope * Year

Note that the Year is the independent variable and Sales is the dependent variable.

Develop a two tail test for the theory that the slope of the regression line is different from zero.
