- The concentration (in nanograms / ml) of plasma epinephrine were measured
for ten dogs uner isoflurane, halothane, and cyclopropane anesthesia; the
measurements are given in the following table (Perry, et al 1974). Is there
a difference in treatment effects?

These data are available on the WWW in the directory OtherData,
under the file name dogs.dat The three
columns of the data set represent, in order, Anesthetic (1=isoflurane, 2=halothane,
3=cyclopropane), Dog id, and epinephrine level.

- The following data from the calibration of a proving ring, a device for
measuring force (Hockersmith and Ku, 1969). Examine the plot of deflection vs
load, fit deflection as a linear function of load, and assess the adequacy of
the linear model. Can you construct a better model?

- Coswell (1973) studied a method of measuring resistance to breathing in
children. The table below lists total respiratory resistance and height for
a group of children with cystic fibrosis. Is there a relationship between
height and resistance for these children?

Resistance. [Source: Rice, 1995: 562].
