![6) You investigate the relationship between height and dbh (diameter at breast height) of oak trees. You get the
following results:
dbh (cm):
height(m):

Read the data into R.
(a) Calculate the following using R: X, y, SS, S.
(Note that to get SS, or SS, you can just ask R for the variance (var) or standard deviation, and
then do the appropriate calculation).
(b) Perform a complete test of the hypothesis that there is
out all the appropriate steps of a regular hypothesis test (give Ho, H1, a, your decision, etc.)
difference in height as dbh increases. Write
(c) Give the equation of the least squares line (Write it out, don't just hand in a printout!!)
7) Finally do the following:
(a) create a residual plot for the analysis you did in (6) and comment on it (is it okay or do you see any
problems?)
(b) create a q-q plot of the residuals and comment on it.
(c) Write down the value of R², and interpet it (do not use "adjusted" R').
