1.1 AN OVERVIEW OF STATISTICS
1.1 TRY IT YOURSELF SOLUTIONS
1. The population consists of the responses of all ninth to twelfth graders in the United States. The
DR
sample consists of the responses of the 1501 ninth to twelfth graders in the survey. The sample data
set consists of 1215 ninth to twelfth graders who said leaders today are more concerned with their
own agenda than with achieving the overall goals of the organization they serve and 286 ninth to
twelfth graders who did not say that.
EA
2a. Population parameter, because the total spent on employees’ salaries, $5,150,694, is based on the
entire company.
M
b. Sample statistic, because 43% is based on a subset of the population.
3a. The population consists of the responses of all U.S. adults, and the sample consists of the responses of
SH
the 1000 U.S. adults in the study.
b. The part of this study that represents the descriptive branch of statistics involves the statement “three
out of four adults will consult with their physician or pharmacist and only 8% visit a medication-
UB
specific website [when they have a question about their medication].”
c. A possible inference drawn from the study is that most adults consult with their physician or
pharmacist when they have a question about their medication.

1. A sample is a subset of a population.
2. It is usually impractical (too expensive and/or time consuming) to obtain all the population data.
VI
3. A parameter is a numerical description of a population characteristic. A statistic is a numerical
description of a sample characteristic.
A?
4. The two main branches of statistics are descriptive statistics and inferential statistics.
5. False. A statistic is a numerical measure that describes a sample characteristic.
?
6. True
?
7. True
8. False. Inferential statistics involves using a sample to draw conclusions about a population.
9. False. A population is the collection of all outcomes, responses, measurements, or counts that are of
interest.
