ASW ESBE (5e) Chapter 1
Solutions to Selected Problems
2.
a.
9 elements, 1 for each row of the table.
b. 5 variables, counting the name of the property (NOTE: The textbook
answer key states 4 variables, NOT counting the name of the property.
This
is incorrect.)
c.
Name of property is qualitative (and nominal).
Country is qualitative (and nominal).
Room rate is qualitative (and ordinal).
Number of rooms is quantitative (and discrete).
Overall score is quantitative (and interval).
d. Property name is nominal, country is nominal; room rate is ordinal;
number of rooms is ratio, and overall score is interval.
(e. Population?
All European hotels surveyed of the subscribers.
3.
a.
Average number of rooms = 808/9 = 89.78 or approximately 90 rooms
per hotel on average.
b. Average score = 732.1/9 = 81.3.
c.
2 of 9 are located in England; so approximately 22% of all sampled hotels
are located in England.
If the sample is representative of the population (and that’s a big if), then
22% of all European hotels surveyed of the subscribers are located in
England.
d. 4 of 9 have a room rate of $$; approximately 44% of all sampled hotels
have moderately priced high season rates.
If the sample is representative of the population, then 44% of all European
hotels surveyed of the subscribers have moderately priced high season rates.
4.
a.
10 elements, 1 on each row.

View Full Documentb. All brands and models of minisystems manufactured.
c.
Average price for sampled minisystems = 3140/10 = $314.
d. Average price for all minisystems = $314.
(e. Assumption for d?
The sample is representative of the population.)
5.
a.
6 variables, counting brand and model.
b. Qualitative:
Brand and model (and nominal).
Sound quality (and ordinal).
FM tuning sensitivity and selectivity is qualitative (and ordinal).
Quantitative:
Price (and continuous and ratio).
CD capacity (and discrete and ratio).
Number of tape decks (and discrete and ratio).
c.
Average CD capacity = 30/10 = 3.
(Inference:
If the sample is representative of the population of all
minisystems, then any minisytem is expected to have capacity for 3 CDs.)
d.

=
(Inference:
If the sample is representative of the population of all
minisystems, then 70% of all minisytems are rated very good or excellent
for their FM tuning quality.)
