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.

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.
