Question
Situation: The Ipod Touch has been out for two years
now and a lot of data has been collected.
Relevant Relationship:
There is a functional relationship between Price of an
IPod Touch,p and Weekly Demand,s.
Below is a table of data that have been collected
Price,p,($) Weekly Demand, s,(1,000s)
150
170
190
210
230
250
A.. Find the linear model that best fits this data using
regression and enter the model below
211
205
196
186
182
168
(for entry round the linear parameter value to nearest
0.01 and constant parameter to nearest 1)
S = T(p)
=
B. The squared correlation coefficient r² was
Select an answer 0.95
(note: values less than 0.95 MAY mean the model is
not appropriate for making predictions)
Now answer these two questions using the
UNROUNDED model parameters
C. What does the model predict will be the weekly
demand if the price of an ipod touch is $231 ?
(nearest 100)
D. According to the model at what should the price be
set in order to have a weekly demand of 247,200 ipod
Touches? $
(nearest $1)
Note: In the "real" world Apple sold about 20 million
Ipod Touch's from Sept. 2007-Sept. 2009 Answer
