Statistical Reasoning for Everyday Life
Chapter 1 (Speaking of Statistics) Exam, form A
MULTIPLE CHOICE. Choose the one alternative that best completes the statement or
answers the question.
For problems 1 and 2, determine whether the evaluated group is a population or a sample.
1) The average (mean) age of all 63 Associate Professors at Cliffton University is 47 years.
A) Population B) Sample
2) A researcher examines the property tax records of 84 property owners in one city and finds that 17%
are behind in their tax payments.
A) Population B) Sample
For problems 3 and 4, determine whether the given value is a statistic or a parameter.
3) The average (mean) age of all 63 Associate Professors at Cliffton University is 47 years.
A) Statistic B) Parameter
4) A researcher examines the property tax records of 84 property owners in one city and finds that 17%
are behind in their tax payments.
A) Statistic B) Parameter
5) Following the Republican National Convention, a poll of 600 voters in a central Illinois community
showed that 57% expected the Republican ticket to win over the Democrat ticket no matter whom the
Democrats chose for vice-president. The margin of error was 4 percentage points. There are 25,000
registered voters in the community. Which range of values is likely to contain the population
parameter?
A) 13,250 to 15,250 B) 24,400 to 25,600
C) 318 to 366 D) 53% to 61%
6) A poll of 488 citizens of Normal, Illinois, showed that 65% favored strict enforcement of speed limits
with a margin of error of 4%. A second poll of 495 citizens of the same town showed that 34% favored
strict enforcement of speed limits. Assuming that proper sampling techniques were used in both polls,
one may conclude that
A) the percent of the population that favors strict enforcement of speed limits is 49.5% \uf0b1 8%.
B) the percent of the population that favors strict enforcement of speed limits is 49.5% \uf0b1 4%.
C) one or both of the samples may have been unlikely samples from the population.
D) the percent of the population that favors strict enforcement of speed limits is 65% \uf0b1 8%.
7) A poll of 700 attendees of the Taste of Chicago showed that 445 attendees, 65% of the sample,
believed that the food was overpriced. It is estimated that 1,250,000 people attend the Taste. Although
65% plus or minus 5% of attendees believe that the food is overpriced, the Taste is a popular event.
The raw data of the study is (are)
A) 65% of the sample.
B) 700 attendees, 455 attendees.
C) 1,250,000 attendees, 700 attendees, 455 attendees.
D) (60%, 70%)
8) A student wanted to know the favorite lunch at a large high school with a closed campus. What is the
first step in conducting a statistical study to answer the question?
A) Select a random sample of students.
B) Precisely state the goal of the study.
C) Select a random sample of students and teachers.
D) Select a random sample of teachers.<\/p>\n\n\n\n

10) A researcher determines that 17% of 84 property owners in a large city are behind in their tax
payments.
A) Census data B) Sample data
For problems 11 and 12, select the most representative sample of the population of interest.

C) A randomly selected group of 30 junior high students leaving the public library
D) The group of 30 junior high students attending the birthday party of the researcher\u2019s child
For problems 13 and 14, identify the sampling technique that was used.
