d. Education and smoking are unrelated.
e. An educated person smokes 73 cigarettes a day.

A researcher had calculated the sample chiÂsquare test statistic to be equal to χ2= 7.71.
For an alpha level of 0.10 and 4 degrees of freedom, the critical value of the chi-square
statistic is 7.78. The appropriate conclusion is that the
a. Sample result is likely to be attributed to chance alone.
b. Null hypothesis should not be rejected.
c. Null hypothesis should be rejected.
d. Both a and b.
e. Alternative hypothesis is true.

behaviors. Which of the following helps eliminate this type of error?

intended recipient.
a. True
b. False
Which of the following is true regarding the standarddeviatio?
a. It indicates the degree of variation in the values in such a way as to be translatable
into a normal curve.
b. One standard deviation above and below the midpoint in a normal distribution
includes approximately 68% of the area underneath the curve.
c. + or - 1.96 standard deviations above and below the midpoint in a normal distribution
includes 95% of the area underneath the curve.
d. The standard deviation can be approximated by dividing the range of the data by 6.
e. All of the above are correct.

One of the major problems with mail surveys is nonresponse bias. In an effort to
minimize this, a researcher decides to limit the sample to his personal friends from
whom he is sure to get replies. This is an example of a
a. probability sample.
b. nonprobability sample.
c. random sample.
d. sequential sample.
e. quota sample.

a. True
b. False

b. Nielsen
c. Dun & Bradstreet
d. The Federal Communications Commission (FCC)
e. GfK Group
The observation method
a. Cannot measure all consumer characteristics precisely but can give very good
estimates for awareness, intentions, motivations, and past behavior.
b. Is limited in that only behaviors can be observed.
c. Is considered to be more objective than the communication method.
d. Is a faster means of data collection than the communication method because a
detailed questionnaire does not have to be prepared, and observers can quickly record
many observations.
e. Requires development of sophisticated procedures to be effective.
