Introduction
1.1 a. The population of interest to the researchers is the population of all young women who
recently participated in a STEM program.
b. The sample is the set of 159 young women who were recruited to complete an on-line
survey.
c. We could infer that approximately 27% of all young women who recently participated in a
STEM program felt that participation in the STEM program increased their interest in
science.
1.2 a. The experimental units for this study are the buried steel pipe locations at a petrochemical
plant in Turkey.
b. The sample is the 19 different randomly selected buried pipe locations at a petrochemical
plant in Turkey.
c. The population is the set of all buried steel pipe locations.
d. This is an example of inferential statistics. The researchers want to see if one test is more
desirable than the other.
1.3 There are two populations – male students at Griffin University who were video game players
and male students at Griffin University who were not video game players. There were two
samples - those male students in the 65 chosen who were video game players and those male
students in the 65 chosen who were not video game players.
1.4 a. The experimental units for this study are the new software development projects.
b. The population is the set of all new software development projects.
c. In the sample, 15 of the 24 or 62.5% of the sample projects were successfully implemented.
We can infer that approximately 62.5% of all software development projects will be
successful.
1.5 a. The experimental units for this study are the earthquakes.
b. The data from the 15 earthquakes represent a sample. There are many more than 15
earthquakes from around the world. Only 15 of the many were studied.

1.6 a. There are two populations for this study – the water flow required to effectively cool
batches of tomatoes for each of the two systems used in preparing tomatoes for market.
The samples are the water flows required to effectively cool the 20 batches of tomatoes for
each of the two systems. The type of inference to be made for this problem would be to
determine if the new system uses less water than the current system.
b. We could find the mean water flow for the new system and the water flow for the current
system. We could then test to see if there was a difference in the mean water flows between
the two systems.
1.7 a. The variable measured is the level of carbon monoxide gas in the atmosphere. The
experimental unit is the atmosphere at the Cold Bay, Alaska, weather station each week.
b. If we are interested in only the weekly carbon monoxide values at the Cold Bay station for
the years 2000-2002, then this data represents the population because all that data were
collected.
1.8 The population is all the items coming off an assembly line. The sample would be the items
selected from the assembly line to check for defectives. One would infer the proportion of all
items coming off the assembly line that are defective based on the sample proportion of
defective items.
1.9 a. Sampling method would be qualitative.
b. Effective stress level would be quantitative.
c. Damping ratio would be quantitative.
1.10 The qualitative variables are country of operator/owner, primary use, and class of orbit. The
quantitative variables are longitudinal position, apogee, launch mass, usable electric power, and
expected lifetime.
1.11 a. Town where sample was collected is qualitative.
b. Type of water supply is qualitative.
c. Acidic level is quantitative.
d. Turbidity level is quantitative.
e. Temperature is quantitative.
f. Number of fecal coliforms per 100 milliliters is quantitative.
g. Free chlorine-residual is quantitative.
h. Presence of hydrogen sulfide is qualitative.
1.12 a. Flight capability is qualitative.
b. Habitat type is qualitative.
