Solution :
a). The required linear regression model is
Price = 
b). The 
for the variable "Age of part" is 0.0000
Since the is less than 0.05, so it is significant to the model.
The p-value for the variable "Number of bidders" is 0.1940
Since is not less than 
, so it is significant to the model.
c). We cannot say that model is significant because variable " the number of bidders" is not significant.
But as both variables have positive coefficient so as the variable increases the price received for the item also increased.
Given:
USD: 104.51
Mexican pesos: 1,322.14
1,322.14 / 104.51 = 12.65
1 US Dollar is equal to 12.65 Mexican Pesos
or
104.51 / 1,322.14 = 0.079
1 Mexican peso is equal to 0.079 US Dollars.
