8.Suppose we are given three groups with the following data values:
G1 : 17, 22, 25, 32
G2 : 16, 24, 30, 42
G3 : 10, 29, 30, 31.
Construct an ANOVA table for these groups and determine if we have
evidence that the population means for these groups are different.
Use α = 0.05.

An experiment has a single factor with five groups and three
values in each group. In determining the among-group variation,
there are 4 degrees of freedom. In determining the within-group
variation, there are 20 degrees of freedom. In determining the
total variation, there are 24 degrees of freedom. Also, note that
SSA= 96, SSW=160, SST=256, MSA=24, MSW=8, and
FSTAT=3.

Studies are often done by pharmaceutical companies to determine
the effectiveness of a treatment program. Suppose that a new AIDS
antibody drug is currently under study. It is given to patients
once the AIDS symptoms have revealed themselves. Of interest is the
average length of time in months patients live once starting the
treatment. Two researchers each follow a different set of 40 AIDS
patients from the start of treatment until their deaths. The
following data (in months) are collected....

We want to compare the
average gas mileage of American-made cars vs. Japanese-made
cars.
The claim is that the Japanese cars and American cars do not get
the same gas mileage.
Use the list data below to test the hypothesis that the Japanese
cars and American cars do not get the same gas mileage.
The American cars are in list1 and the Japanese cars in list2
below
We do not know whether the mileages are normally distributed or
not, but...

Assume that Data Set C depicts scores for 30
individuals who participated in a two-way independent groups
design. Analyze the data using a two-way ANOVA and complete an
ANOVA table reporting the relevant DD, df, MS, and Fs. Make sure to
also report each of your critical values and indicate whether you
would reject each of your three null hypotheses (i.e., main effect
of A, main effect of B, interaction of A x B)
