The marketing group and Rings Are Us is trying to predict if undergraduate or graduate students are more inclined to purchase (y = 1) or not purchase (y=0) a class ring at graduation. Using the following count on the training data set, calculate the conditional probability of both to determine which should be classified to the purchase group. Undergraduate (x = 1) 70 Graduate (x = 0) 100 Purchase (y = 1) No Purchase (y = 0) 30 110 Multiple Choice Undergraduate 0.70 > 0.272; Graduate 0.428 <0.272. The undergraduate is assigned to the purchaser group. Undergraduate 0.30 <0.20; Graduate 0.524 > 0.476. The graduate is assigned to the purchaser group. Undergraduate 0.70 > 0.30; Graduate 0.476<0.524. The undergraduate is assigned to the purchaser group. Undergraduate 0.303 > 0.272; Graduate 0.476< 0.524. The undergraduate is assigned to the purchaser group.
