Question
Let’s return to the model of iPod prices on eBay that was developed in
Exercise 7 in Chapter 3. That equation was:
PRICEi = 109.24 + 54.99NEWi - 20.44SCRATCHi + 0.73BIDRSi
15.342 15.112 10.592
t = 10.28 -4.00 1.23
N = 215 F = 55.09
where: PRICEi = the price at which the ith iPod sold on eBay
NEWi = a dummy variable equal to 1 if the ith iPod was
new, 0 otherwise
SCRATCHi = a dummy variable equal to 1 if the ith iPod had a
minor cosmetic defect, 0 otherwise
BIDRSi = the number of bidders on the ith iPod
a. Create and test hypotheses for the coefficients of NEW and
SCRATCH at the 5-percent level.
