K When cars from country A's automobile manufacturers started being imported to country B, they were given very poor quality ratings. That started changing several years ago. The improved quality started being seen in a 2004 study. Results were based on responses from more than 62,000 purchasers and lessors of new-model-year cars and trucks, who were surveyed after 90 days of ownership. The initial quality is measured by the number of problems per 100 vehicles (PP100). The PP100 data from the interval 1998-2004 are shown in the accompanying table. Complete parts a through c. Click the icon to view the data. a. Produce a regression equation to predict the PP100 for vehicles in the model y₁ = Po +B1x1 + B2x2 + ε, where 1 if from country B 1 if from country C X₁₁ = and X2 = 0 if not from country B 0 if not from country C y = -( D x + Dx + (Round to one decimal place as needed.)
