A manufacturer is interested in selecting one of three companies to deliver (by truck) its
product to its distributors and wholesalers in a certain area. Each of the companies has
different operating procedures and uses different routes. Assuming that certain
minimum standards for delivery time are achieved, the manufacturer wants to select the
company with the lowest unit shipping cost.
In addition, the manufacturer believes that the type of packaging used for the product
may have an impact on shipping cost and is considering two types of packaging. It is
unknown whether or not any of the three companies under consideration is better
equipped to handle either type of packaging.
After using each of the companies for five deliveries of the product with each of the
types of packaging (thus, each company made a total of 10 deliveries, with all
deliveries under similar circumstances), the shipping costs per unit were calculated and
are shown below:

A study was done in an attempt to discriminate between the listeners of three popular
AM radio stations during the morning "drive-time" period. The following demographic
variables were used in the analysis: age, income, education, marital status, number of
children at home, and gender. Use the information to answer the following two
questions?
How many discriminant functions will be generated in this analysis?
a. 1
b. 2
c. 3
d. 4
e. None of the above.

b. 2
c. 3
d. 4
e. 5

You would like to determine the demographic characteristics of owners of recreational
vehicles. The appropriate research strategy would be
a. analysis of insight'‘stimulating examples.
b. exploratory research.
c. descriptive research.
d. field experiment.
e. laboratory research.
The researcher can estimate the impact of the experimental stimulus in the
four'‘group'‘six'‘study design when there is an interactive testing effect by comparing
a. the second control group and the first experimental group.
b. the two experimental groups.
c. the second experimental and control groups.

Mary Marsh, head aerobic instructor at Tuff-it-Out Fitness Centers, wanted to estimate
the proportion of all 19-39 year olds who aerobically exercise at least once each week.
Mary would like the estimate to be within plus or minus 3 percentage points of the
mean and she would like to have 90 percent confidence (z=1.645) in her results. Mary
estimates the population proportion at .40. The required sample size is
a. 8.
b. 73.
c. 482.
d. 722.
e. 964.
Quota samples are typically selected so that the distribution of a characteristic or
characteristics in the sample matches the distribution of these same characteristic(s) in
the population. With respect to the representativeness of quota samples, it can thus be
said that
a. a quota sample may be very far off the mark with respect to other important
characteristics likely to influence the result but that were not used as controls when
selecting the sample.
b. the fact that the distribution of the characteristic in the sample parallels the
distribution in the population does not guarantee that the sample is representative.
c. the quota assigned each field worker should exactly mirror the distribution of the
control characteristic(s) in the population.
d. a and b are true.
e. a, b, and c are true.
Attitude represents
a. a predisposition to respond to an object.
b. behavior toward an object.
c. a person's ideas, convictions, or liking for a specific object or idea.
d. all of the above.
e. a and c only.
Neural networks:
a.are believed to describe fairly accurately neural transmissions in the brain.
b.require assumptions of multivariate normality.
c.require large data bases.
d.require ratio level data.
e.require the user to specify the beta-weights.
Which of the following statements is FALSE?
a. Decision problem formulation is the first step in the research process.
b. Sampling error is the key error associated with a research project.
c. The stages in the research process are interrelated in that a decision with respect to
one stage affect is decisions made at the other stages as well.
d. Revision of the decision problem is not possible after data have been collected.
e. b and d are false.
