LenKa [72]

Solution :

a). The required linear regression model is

Price = $-1242.986 + 75.017 \times \text{age of part} + 13.973 \times \text{ number of bidders}$

b). The $\text{p-value}$ for the variable "Age of part" is 0.0000

Since the $\text{p-value}$ 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 $\text{p-value}$  is not 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.

ludmilkaskok [199]

Do this by taking 30% of 120k to find out how much more money you would make in comparison to a non-college grad, 120,000*.3=36,000. This means a college grad would make $36,000 more than a non-college grad.
