It was hypothesized that the number of bottles of an imported premium beer sold per evening in the restaurants of a city depends linearly on the average costs of meals in the restaurants. Average cost in dollars of a meal = $350, and SD = 25.5; Average number of bottles sold per evening = 180 and SD = 16.0; r = 0.6 Assume that the scatter diagram has linear regression is homoscedastic and is football-shaped. The average cost in dollars of a meal that is $299 is closet to:
  • $161
  • $150
  • $165
  • $158
