Homework Statement
[PLAIN]http://img822.imageshack.us/img822/4421/statsii.jpg
The Attempt at a Solution
Done parts (a) and (b). How do I do parts (c) and (d)?
Is the simple linear regression model just [itex]Y_i=\beta_0+\beta_1 X_i + \varepsilon_i[/itex] where [itex]\varepsilon_i \stackrel {\text{i.i.d.}}{\sim} N(0,\sigma^2)[/itex]
Does [itex]X_i[/itex] respresent the age of the bus and [itex]Y_i[/itex] the maintenance cost?
