g XYZ Retail Company has a demand for 1,000 calculators each year. The supplier charges XYZ a cost per calculator of $60. It costs XYZ $40 to place an order, and the carrying cost is 20% of the calculator unit cost. XYZ has two options when it comes to ordering calculators from its supplier. Option 1: It costs XYZ $60 per calculator, which provides no discount, but there is no limit as to how many calculators it can order. Option 2: If XYZ orders 200 calculators in bulk, it will receive a 3% discount on the cost of calculators from its supplier. Question: If XYZ does not take the discount (i. e., chooses Option 1) what will its total cost be to buy the inventory. (The TC equation includes TCH (or TCC), TCO, and PD.)

Acompany is developing a new high­performance wax for cross country ski racing. in order to justify the price marketingwants, the wax needs to be very fast. specifically, the mean time to finish their standard test course should be less thanseconds for a former olympic champion. to test it, the champion will ski the course 8 times. the champion's times(selected at random) are 59.9 61.9 48.8 52.2 46.6 45.3 50.6 and 41.1 seconds to complete the test course. complete parts a and b below. a) should they market the wax? assume the assumptions and conditions for appropriate hypothesis testing are metfor the sample. assume=0.05. what are the null and alternative hypotheses? choose the correct answer below. b) suppose they decide not to market the wax after the test, but it turns out that the wax really does lower the champion'saverage time to less thanseconds. what kind of error have they made? explain the impact to the company of such anerror.
