Elementary operations on vectors; sum, modulus, unit vector, scalar multiple. 

Putting algebraic fractions into their simplest forms

A multiple linear regression model of the form:

\[Y=\beta_0+\beta_1X_1+ \beta_2X_2+\beta_3X_3+\beta_4X_4+\epsilon \]

is fitted to some data in Minitab which generates a table showing estimates of the parameters with associated $p$-values. Determine which variable to exclude first.
