X$10$ Do you believe you need a DVD player?

X$11$ How likely are you to purchase a DVD player?

X$16$ Are you an early adopter or innovator?

X$15$ total annual household income before taxes

X$14$ level of electronics products ownership that best describes you

Based on the above regression table answer the following questions:

a$)$ How good is this model overall? How did you know?

b$)$ Interpret the coefficients of variables that you consider has significant impact on Dependent variable. Why?
