A car dealer who sells only late-model luxury cars recently hired a new salesperson and believes that this salesperson is selling at lower markups. He knows that the long-run average markup in his lot is $5,600. He takes a random sample of 16 of the new salesperson's sales and finds an average markup of $5,000 and a standard deviation of $800. Assume the markups are normally distributed, and use a 2% significance level. Which of the following correctly represents the hypotheses for the car dealer? Hou = $5,600 H:H # $5,600 Ho:u > $5,600 Ha:! <$5,600 (a) (b) Hou > $5,000 Ha:μ< $5,000 Ho:u < $5,600 Ha:u > $5,600 (c) (d)
