Deborah Mitz buys Breathalyzer test sets for the Police Department. The quality of the test sets from her two suppliers is indicated in the following table: (image attach) For example, the probability of getting a batch of tests that are 1% defective from Loomba Technology is .70. Because Mitz orders 10,000 tests per order, this would mean that there is a .7 probability of getting 100 defective tests out of the 10,000 tests if Loomba Technology is used to fill the order. A defective Breathalyzer test set can be repaired for $0.50. Although the quality of the test sets of the second supplier, Stewart-Douglas Enterprises, is lower, it will sell an order of 10,000 test sets for $37 less than Loomba. a) Develop a decision tree. b) Which supplier should Kellogg use?
