We wish to determine the impact of Specification Buying, X11, on
Satisfaction Level, X10. To do so we will split the Hatco data file
into two separate data sets based on the Specification Buying, X11.
This variable has two categories:
1=employs total value analysis approach, evaluating each
purchase separately;
0 = use of specification buying.
Sort the entire Hatco data set based on Specification Buying.
This will create two separate groups of records. Those records with
X11 = 0 and...

(Raw Data, Software Required):
Here we consider a small study on the sleep habits of med students
and non-med students. The study consists of the hours of sleep per
night obtained from 30 non-med students and 25med students. The
sample data is given in the table below. Test the claim that, on
average, the mean hours of sleep for all med students is different
from that for non-med students. Test this claim at the 0.01
significance level.

Wild irises are beautiful flowers found throughout the United
States, Canada, and northern Europe. This problem concerns the
length of the sepal (leaf-like part covering the flower) of
different species of wild iris. Data are based on information taken
from an article by R. A. Fisher in Annals of Eugenics (Vol. 7, part
2, pp. 179 -188). Measurements of sepal length in centimeters from
random samples of Iris setosa (I), Iris versicolor (II), and Iris
virginica (III) are as follows...
