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. (i) You want to test the hypothesis that an additional one year from the time of death to the sale of a painting will increase the price of the painting by $30,000 (30 units in the dependent variable). What is the null hypothesis? (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?
