Yоu believe thаt the time since аn аrtist's death has a large impact оn the price оf their paintings. Using a random sample of oil painting sales (in thousands of dollars; sales) and time from the artist's death to the sale of the painting (in years; Time) you generate the following regression output: oil painting sales = beta_0 + beta_1 * Time.

(ii) You want to test the hypothesis that an additional ten years from the time of death (10 units in Time) to the sale of a painting will increase the price of the painting by $100,000 (100 units in the dependent variable). What is the null hypothesis?
