7 & 8 Suppose the Current Supplier's motor costs the company $37.75 per motor and the 7. Which Supplier is preferred (that is, is most reliabile, lowest total cost)? New Supplier's motor will cost the company $39.15 per motor. If the company plans to offer an 1, 100 hour warranty and to replace any motor that fails at the company's 8. What is the net savings annually using the most reliable motor? expense (which includes the cost of the replacement motor plus approximately $60 labor per unit for the service call to install it), which supplier should the company use and what is the net annual savings with this supplier (relative to the other one)? Assume that in a typical year the company uses 36,500 motors and each treadmill has, one motor. Show any computations for your answers in this worksheet to the right as indicated. Computations over here 9 Suppose we take another random sample of n=18 of the Current Supplier's motors. What is the probability the average of the new sample exceeds 1250 hours? 10 Suppose we take another random sample of n=18 of the New Supplier's motors. What is the probability the average of the new sample exceeds 1500 hours? 11 & 12 Ninety percent of the averages of future random samples of n=18 from the New Lower bound Supplier should fall between what two values? Upper bound
